debug a mobile website applicattion $50

I built a mobile app website in Visual studio pro and I can't get it to render properly. I keep getting the error: " line1 column 2: start tag, in valid element name. This application needs to be rendering properly by Tuesday August 7th 2012. I am willing to start at $50 since. I think this could be a simple fix. I will make a decision promptly about who I am hiring. Happy Sunday.
