Profiles / Cam Directory

I'm looking for a PHP Cam Directory script or a business directory one that functions in a similar way so it can be easily customised to do the same thing. To have categories like a cam site and for these to be listed on a front page. Basically I want Models to be able to log in, create/maintain a user profile (with a friendly URL), upload pics etc and it to be connected to social networks (twitter etc). On this profile will be buttons to launch premium web cam or Phone sessions. The actual technology of the Cam/Phone stuff is already in place, I'm just looking for a decent wrapping for it. It can be open source, a Wordpress Plugin or a reasonably priced flexible commercial script. Any recommendations?
