Domain parking software in PHP

Need a total script designed to provide a domain parking service website. Similiar to scripts that are used on parked.com, trafficz.com, parkingdots.com, goldkey.com if you are familiar with those websites at all. It will give users the ability to park their domains, sell and buy domains with other people. Keep full statistics for each parked domain, including views, clicks, etc. Domains can be optimized by entering a specific keyword related to that particular domain, so that targeted adverts can be displayed on the parking page. More details can be discussed then.
