Income Tax Disclosure [Abstract]  
Income taxes

We recognized income tax expense of $43,022 and $43,401 during the three and nine month periods ended September 30, 2014, respectively, based on our projections of future profitability.  We recognized income tax expense of $72,294 and $475,294 during the three and nine month periods ended September 30, 2013, respectively. The variation between the company’s annual effective rate and the Unites States statutory rate of 34% is primarily due to state income taxes, foreign income taxes, the effects of stock compensation, and disallowed interest expense.
