Help! I need capital!

I recently opened up a Google Adwords account and have been doing really well. The more money I spend, the more I make.

Problem is, I have to pay Google right away for my ads, but I don't get my commission checks for a couple of weeks. My adspend is getting high, but I am making money, so I don't want to scale it back, but I'm getting to the point where I can't afford it anymore

Any ideas on how to get capital? My credit sucks (I'm paying bills down, but my score is still bad) so I can't get a credit card... at least not easily.

Any help?

Do you have friends of family who could help?

If you showed them the plan as a business model it could convince them.

of course there is the danger of being pulled by adsense after the adwords spend but you seem like a sensible person..
