Social Network style site required

Hi i am currently looking over some social network scripts, open source and paid. I require a few social network sites, and i need them to become their own networks. one of them is UKan UK Adult Network. where as it will have dating sites for various niche sites, with also possibly few other tabs. TBC Another i have wanted to do is a social Start Up website where as young entrepeneurs register and try to start a business by connecting through possibly a third party TBC so young people can connect with other similar aged people who could possibly help them in parts of their projects, and possibly team up and look at the chance to get investment from (another site that i would like done a croudfunding script), which can help them connect with mentours and also investors. Please bid for a complete design, build, fully functional testing of the UKAN website and social site. If you do this job well the 2nd can follow, unless someone bids on this seperately.
