Video Sharing social Networking site

Hello, i need someone to create a more fun, and innovative video sharing site. The site has to be created from the bottom, with great fun design. I will also need the site to have all the functions of youtube with little functions of face book. -----The site includes------ A Vibrant homepage with a live chat box. Users are able to make clean and simple profiles where they uploaded videos show. I will like to have different categories for videos. There is alot more i will discuss with the winner. I will not discriminate against Freelancers with no history, but you would have to show me a visual of the begining of my site. Before you get paid and you will get paid in increments. in order to get rewarded you must show me a portfolio showing that you can create a social networking site, and/or video sharing site/ and a vibrant fun design. Remember site must have all the functions of youtube. Including fast video streaming. As well as live video confrences. I am shooting for $600 dollars, but i'm guessing the bids are going to be higher. Anything close to my price would be considered first. Thank you
