566966 Advertisment Module for a Search Engine

I have search engine, which i need to develop a my own paid ad-words type account to advertisers all these needs to be custom coded. Remember that my search engine has built on core, So this custom module also needs to be built from stretch, i already have the kyword data in the back-end with MySQL. I dont expect too much of functionality just the basic functionality for the advertisers to pay via paypal, add keywords and set the adword live, and view statistics. However coding needs to be 1. Object oriented 2. MVC based 3. High quality front end design with css3 and Jquery Ajax. 4. Optimised for high server usage 5. good knowledge of UTF8 data handling is needed..
