   Net income  $4,052,479   $5,850,998 
Denominator:          
   Denominator for basic earnings per share:          
      Weighted average shares outstanding   3,356,383    3,327,867 
   Effect of dilutive employee stock options   368,220    249,956 
   Denominator for dilutive earnings per share   3,724,603    3,577,823 
   Basic earnings per share  $1.21   $1.76
