Angel for the site setup fees up-till it is running would not be a big deal. If u wish we can split cost. later from each transaction posted we can have such initial low fees, then if the displayed ad is sold we have a percentage from the total value. Actually it can be both ways. We cover our cost and after, all the money can go as u mentioned. If you are serious enough i can get sponsers.
