Ads website clone, Gumtree, ozadz.com

I need some to take the best features of gumtree and ozads and make me a cloned listing site, but it needs to integrate with facebook, twitter and other social networks. I.e. people can choose to "boost" there ad if they prmote it via thiere linked twitter or facebook account ( users should also be able to have annoyomous accounts) Users need to register to post an ad though. Thats it
