Going Concern Evaluation [Line Items]
Substantial doubt about going concern, management's evaluation	In connection with preparing consolidated financial statements for the three and six months ended June 30, 2017, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to continue as a going concern within one year from the date that the financial statements are issued. The Company considered the following:  Operating losses for ten consecutive quarters  Negative cash flow from operating activities for six consecutive quarters  Depressed stock price resulting in being non-compliant with NASDAQ listing rules to maintain a stock price of $1.00/share  Stockholders’ equity being less than $2.5 million at March 31, 2017 and June 30, 2017 resulting in being non-compliant with NASDAQ listing rules Ordinarily, conditions or events that raise substantial doubt about an entity’s ability to continue as a going concern relate to the entity’s ability to meet its obligations as they become due. The Company evaluated its ability to meet its obligations as they become due within one year from the date that the financial statements are issued by considering the following:  The Company raised $4.0 million of debt financing during the year ended December 31, 2016  The Company has been able to raise capital from short-term loans from insiders  As a result of the Company’s restructurings that were implemented during the three months ended December 31, 2016, and again during the six months ended June 30, 2017, the Company’s cost structure is now in line with its future revenue projections. See Footnote 5 below for additional details regarding restructurings Management believes that the Company will generate enough cash from operations to satisfy its obligations for the next twelve months.
