Adsense Clone

Hi, Need some help developing an advertising website and an advertising solution for buyers. Its sort of similar to adsense and will involve a site placing code on their site to get rewarded. If you have an adsense script already developed this would be useful. The site being developed would then record the number of ads or impressions that joining sites show on their webpages and they would recieve money for it. Equally, ad providers would have to pay to show ads on other sites which have joined. Let me know if you are interested and can do it within this budget! Thanks
