Banner Ad Network (Like Adsense, OpenX, chitika, etc)

Hi, I need to create a banner ad network, basically the publisher generates a code and puts on his webpage, and advertisers create campaigns and bid on CPM, CPC and CPA , so the advertisers that bid more have their ads shown. Advertisers can upload their creatives The ad network will allow category segmentation, channels, and some other simple targeting features (location, browser, operation system, device..), also it will allow conversion tracking and all metrics calculation (revenue, profit, cpm, ecpc, ecpm, etc) Ability to each publisher add multiple sites but each one of them must go through review A very very complete admin panel with almost all possible administration options and all configurable to have multiple user levels. Powerful reporting for publishers, advertisers and administrators. System must support payments like: paypal, bank transfer, wire... Performance optimize for large network like cache, CDN (amazon s3 and cloudfront), memcache... Advanced Anti fraud clicks Billing Interface for all clients Advertisers and Publishers self sign up Revenue share by global system settings and per publishers Support Zone with sizes base on IAB Ad serving base on target, publisher website content, refer and search words Advertisers and Publisher can get more earning by refer other user Powerful logging and debugging system Advanced User Management Return credit to advertisers if publishers get banned Coupon code system to give credit to users Supports smartphone ad serving like iOS and Android Supports blocking web spiders and bots Supports automatic ad rotation Supports delivery and tracking of all rich media ads (flash, .gif, jpg, html, java, png, etc) I prefer someone that has experience with ad networks and has used some. I can provide you with some examples of similar ad networks Must be done using some PHP framework (zend, symfony, yiiframework, etc) You also need to take care of the layout or find a designer to do it.
