I agree with these guys regarding your adsense blocks, you definitely need to move them to better spots. Do what Manish suggested.

I would definitely try to get an optin form in there. I know it won't help with a bill that is due, but that is the best way to get people back to your site and buying.

As for your short term problem, try fiverr.com or perhaps get a quick job on odesk.com or elance.com. You only have a few weeks, so adsense isn't going to help.

Good luck,

Bill
