Based on their last 10Q revenues, I would say IZEA is undervalued.  The current market value has IZEA around 5 million, but I would value you them 3 times this (based on a quick look over of their latest 10Q).  The company does need to focus on becoming profitable by lowering their costs, expenses, etc..  Should be a good company to keep an eye on.  I will have further look into the financials to see what is there to better determine a value.
