I got 100.00 google adwords offer that i can use



How about an adwords campaign for cheeto-eating-hookers? Sounds like an untapped micro-niche to me!
 
Don't do anything with that voucher yet. You probably have 30 days or so to use it, so spend the next 25 getting ready.

Do niche research, keyword research, build (yes, I said build NOT rip) a landing page, build a second landing page, install Prosper202, OpenX, get the codes on the pages, and so on and so forth until you're ready to launch.
