Exhibit 3.30

AMENDED AND RESTATED

BYLAWS

OF

SHAFFER & ASSOCIATES, INC.

ARTICLE I. MEETINGS OF SHAREHOLDERS

Section 1. Annual Meeting. The annual meeting of the shareholders of the Corporation for the election of directors and the transaction of other business shall be held during the month of April each year and on the date and at the time and place that the board of directors determines. If any annual meeting is not held, by oversight or otherwise, a special meeting shall be held as soon as practical, and any business transacted or election held at that meeting shall be as valid as if transacted or held at the annual meeting.

Section 2. Special Meetings. Special meetings of the shareholders for any purpose shall be held when called by the chief executive officer, president or the board of directors, or when demanded in writing by the holders of not less than 20 percent (unless a greater percentage not to exceed 50 percent is required by the Fourth Amended and Restated Articles of Incorporation) of all of the outstanding shares entitled to vote at the meeting. Such demand must be delivered to the Corporation’s secretary. A meeting demanded by shareholders shall be called for a date not less than ten nor more than sixty days after the request is made, unless the shareholders requesting the meeting designate a later date. The secretary shall issue the call for the meeting, unless the president, the board of directors, or shareholders requesting the meeting designate another person to do so. The shareholders at a special meeting may transact only business that is related to the purposes stated in the notice of the special meeting.

Section 3. Place. Meetings of shareholders may be held either within or outside Illinois.

Section 4. Notice. A written notice of each meeting of shareholders, stating the place, day, and hour of the meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered to each shareholder of record entitled to vote at the meeting, not less than ten nor more than sixty days before the date set for the meeting, or in the case of a merger, consolidation, share exchange, dissolution or sale, lease or exchange of assets not less than twenty nor more than sixty days before the date set for the meeting, either personally, by electronic transmission to the extent permitted by the Illinois Business Corporation Act of 1983, as amended from time to time (the “IBCA”) or by first class United States mail, by or at the direction of the president, the secretary, or the officer or other persons calling the meeting. If mailed, the notice shall be considered delivered when it is deposited in the United States mail, postage prepaid, addressed to the shareholder at his address as it appears on the records of the Corporation.

Section 5. Waivers of Notice. Whenever any notice is required to be given to any shareholder of the Corporation under these Bylaws, the Fourth Amended

and Restated Articles of Incorporation or the IBCA, a written waiver of notice, signed anytime by the person entitled to notice shall be equivalent to giving notice. Attendance by a shareholder entitled to notice of a meeting, in person or by proxy, shall constitute a waiver of (a) notice of the meeting, except when the shareholder objects to the holding of the meeting because proper notice was not given.

Section 6. Record Date. For the purpose of determining the shareholders entitled to notice of or to vote at any meeting of shareholders, or shareholders entitled to reeive payment of any dividend, or in order to make a determination of shareholders for any other purpose, the board of directors may either require the stock transfer books to be closed for up to sixty days or fix a record date for such determination of shareholders, which shall be not more than sixty days and for a meeting of shareholders, not less than ten days, or in the case of a merger, consolidation, share exchange, dissolution or sale, lease or exchange of assets, not less than twenty days, immediately preceding the date on which the action requiring the determination is to be taken. However, a record date shall not precede the date upon which the resolution fixing the record date is adopted. If the transfer books are not closed and no record date is set for the determination of shareholders entitled to notice of or to vote at a meeting of shareholders, or shareholders entitled to receive payment of a dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the board of directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of shareholders. When a determination of the shareholders entitled to vote at any meeting has been made, that determination shall apply to any adjournment of the meeting, unless the board of directors fixes a new record date. The board of directors shall fix a new record date if the meeting is adjourned to a date more than 120 days after the date fixed for the original meeting.

Section 7. Shareholder’s List for Meeting. A complete alphabetical list of the names of the shareholders entitled to receive notice of and to vote at the meeting shall be prepared by the secretary or other authorized agent having charge of the stock transfer book. The list shall be arranged by voting group and include each shareholder’s address, and the number, series, and class of shares held. The officer or agent having charge of the transfer books for shares of the Corporation shall prepare such list within twenty days after the record date for a meeting of shareholders or ten days before such meeting, whichever is earlier, and, for a period of ten days prior to such meeting, shall keep such list on file at the registered office of the Corporation and where it shall be subject to inspection by any shareholder, and to copying at the shareholder’s expense, at any time during usual business hours. Such list shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any shareholder during the whole time of the meeting. The original share ledger or transfer book, or a duplicate thereof kept in the State of Illinois, shall be prima facie evidence as to who are the shareholders entitled to examine such list or share ledger or transfer book or to vote at any meeting of shareholders. Any shareholder, his agent or attorney, upon written demand and at his own expense may inspect the list during regular business hours.

If the requirements of this section have not been substantially complied with, the meeting, on the demand of any shareholder in person or by proxy, shall be

2

adjourned until the requirements of this section are met. If no demand for adjournment is made, failure to comply with the requirements of this section does not affect the validity of any action taken at the meeting.

Section 8. Shareholder Quorum and Voting. A majority of the shares entitled to vote, represented in person or by proxy, constitutes a quorum at a meeting of shareholders. If a quorum is present, the affirmative vote of a majority of the shares entitled to vote on the matter is the act of the shareholders unless otherwise provided by law. A shareholder may vote either in person or by proxy executed in writing by the shareholder or his duly authorized attorney-in-fact. After a quorum has been established at a shareholders’ meeting, a withdrawal of shareholders that reduces the number of shareholders entitled to vote at the meeting below the number required for a quorum does not affect the validity of an adjournment of the meeting or an action taken at the meeting prior to the shareholders’ withdrawal.

Authorized but unissued shares, including shares redeemed or otherwise reacquired by the Corporation, and shares of stock of this Corporation owned by another corporation, the majority of the voting stock of which is owned or controlled directly or indirectly by this Corporation, at any meeting shall not be counted in determining the total number of outstanding shares at any time. Shares standing in the name of another corporation, domestic or foreign, may be voted by such officer, agent, proxy or legal representative authorized to vote such shares under the law of incorporation of such corporation. The Corporation may treat the president or chief executive officer of such corporation, together with any other person or office holder indicated by such corporation, as a person or office holder authorized to vote such shares. Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his, her or its name if authority so to do be contained in an appropriate order of the court by which such receiver was appointed. Shares held by an administrator, executor, guardian, or conservator may be voted by him without a transfer of the shares into his name. A trustee may vote shares standing in his name, but no trustee may vote shares that are not transferred into his name. A shareholder whose shares are pledged may vote the shares until the shares have been transferred into the name of the pledgee, and thereafter the pledgee or his nominee shall be entitled to vote the shares unless the instrument creating the pledge provides otherwise.

Section 9. Proxies.

Any shareholder entitled to vote at any meeting of shareholders may vote the shareholder’s shares in person or by proxy. At all meetings of shareholders, a shareholder may appoint a proxy to vote or otherwise act for him, her or it by delivering a valid appointment form to the person so appointed or to a proxy solicitation firm, proxy support service organization or like agent authorized by the person or persons to receive the transmission. Such transmission shall be sent by means considered valid by the IBCA. If an appointment form expressly provides, any proxy holder may appoint, in writing, a substitute to act in his place. An appointment of a proxy is effective when received by the secretary of the Corporation or other officer or agent authorized to

3

tabulate votes. An appointment is valid for up to 11 months unless a longer period is expressly provided in the appointment form. The death or incapacity of the shareholder appointing a proxy does not affect the right of the Corporation to accept the proxy’s authority unless notice of the death or incapacity is received by the secretary or other officer or agent authorized to tabulate votes before the proxy exercises his or her authority under the appointment. An appointment of a proxy is revocable by the shareholder unless the appointment form conspicuously states that it is irrevocable and the appointment is coupled with an interest. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of the IBCA. If the validity of any proxy is questioned, it must be submitted to the secretary of the shareholders’ meeting for examination or to a proxy officer or committee appointed by the person presiding at the meeting. The secretary of the meeting or, if appointed, the proxy officer or committee, shall determine the validity of any proxy submitted and reference by the secretary in the minutes of the meeting to the regularity of a proxy shall be received as prima facie evidence of the facts stated for the purpose of establishing the presence of a quorum at such meeting and for all other purposes.

Section 9. Removal or Resignation of Directors. At a meeting of shareholders called for that purpose, the shareholders, by a vote of the holders of a majority of the shares entitled to vote at an election of directors, may remove any director, or the entire board of directors, with or without cause (provided the notice for such meeting states that a purpose of the meeting is to vote upon the removal of such director who must be named in the notice), and fill any vacancy or vacancies created by the removal (provided the notice for such meeting, if a special meeting, states that a purpose of the meeting is to fill any such vacancy).

Notice of a meeting of the board of directors need not be given to any director who signs a waiver of notice either before or after the meeting. Attendance of a director at a meeting constitutes a waiver of notice of the meeting and all objections to the time and place of the meeting, or the manner in which it has been called or convened, except when the director states, at the beginning of the meeting, or promptly upon arrival at the meeting, any objection to the transaction of business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of any regular or special meeting of the board of directors need be specified in the notice or waiver of notice of the meeting.

A majority of the directors present, whether or not a quorum exists, may adjourn any meeting of the board of directors to another time and place.

If a resignation is made effective at a later date, its board of directors may fill the pending vacancy before the effective date if the board of directors provides that the successor does not take office until the effective date.
