I recommend you to use Geegain Advertising as they are giving $5 for every new sign up. It's not same as it does not contains advanced features that AdWord have but it have all features of AdSense. Agreed...
It seems geegain is based in sri lanka.. hmm never heard of it before your post. I wouldn't come near it before I hear about them in better terms than a question such as "will it work?" The page on wikipedia about them is an orphan page, so no other page is talking about them. Hmm doesn't smell too good. And the $5 to sign up are not enough as an incentive to try something unknown to me.
