Construct a new Profile/Social site

Hello, I am looking for someone who is very confident in PHP to make a clone of a mixture of some other social/profile sites. Ideally you will also be very confident with web design (web 2.0 style) as I have an idea of what I want the site to look like so will need you to come up with this design and create a css, or html template to keep it constant throughout the site and also easy to make updates to if needed. So you must be confident that all your code and design is W3C compliant, with good dialogue and error free etc. I have already worked on quite a bit of the site, and it is online currently, however there is still a lot of work that needs to be done like admin panel, video/photo uploading etc, and the current code is not very good and has a lot of bugs, so I think it will be better to just start from scratch, but you can use the existing site to help see what it is I want functions I want on the site etc… I can give you a lot more information and details about the site and show you the other websites I want it to be like after you get in contact. Please include examples of your previous work, especially if you have worked on profile/social based sites, and show examples of your website design. I have a number of sites that I want to work on so ideally you will be quite cheap and confident that you can work with complex php so I can work with you a lot more in the future. I look forward to hearing from you,
