Adwords and adsense clone

I need a site where advertisers can buy targeted ppc ads through us and something like adsense where a users picks a template and size for the advertisement and it scans the page content and gives the most targetted ads in the network. I need this script to support all xml feed that can be entered in the admin panel like: searchfeed, enhance, abcsearch, [login to view URL], miva, searchfeed and search123 etc.
