Create Ad Sharing WordPress plugin

Hello all, first of all let me introduce you with my requirements. I need WordPress plugin that will show ads by author of the post. Admin Area: - options to add unlimited ads zones that I will be able to call inside the code with simple php line (ticking option that will put or not put available if authors chose to use Custom Ads option) - options to setup default adsense publisher - options to add unlimited donations accounts so as in this example 77% earnings will go to some organizations - options to setup "revenue share" in %. (if I use 23% blog - 77% author - it should show 23% time blog ads and 77% time author ads) Users Area: - users can chose between, Donation, Google Ads and Custom Ads. - Donations - then they are able to use one of organizations (this is connected with 3rd option mentioned earlier on Admin Area) - Google - they are very limited to Google. They are able only to ad pub-CODE (this is only way allowed to use Google Adsense on revenue share webiste) - Custom Ads - they are able to setup their Custom Ads for some zones that are allowed by admin (connected with 1st option on Admin Area) - any changes by authors should be confirmed by admin before activating. Bidders Area: - this is not area in WordPress admin zone, it is just a pure protection from mass responding, so if you want me to consider your bid as real please include the following sentence in the bid or private message please: I will build you AdShare plugin for USD 140. Here is one good example for adsense code that is working but on 100% author revenue share: [login to view URL] I need this plugin to be developed in 8 days. Budget is quite limited to USD 140. I'm sure that some expert PHP / WordPress coder should have any problems with this coding. Happy Bidding, Spiro.
