php /mysql game site

Hi all, i need a gaming site with the following features, you will use an open source CMS (jhoomla). The site is half complete, you can either start from the half or can start from the scratch,i would need a quick turn around. this is all i want : Sign in for members- a voting system on games, this can determine if a game stays in popluar, goes to popular or any other suitable catagrey. Also non members have to wait 15 secs before playing a game, maybe an add page, like the php aracde. * A page for members, they can have there favouite game, proffile etc. * Sign in for game developers- where they can submit there games and contact us, submission can require a link in to us. * Traffic exchange script- most likely an arrow script as used by fishflashgames. ( I will buy this script). * Link code instructions on games for exchanges and general instuctions. * Link page * Intergration so we can automatically upload games from mochi group. THis gives us fresh [login to view URL] accept reject games that are submitted easily. * A content management system backend, for game , member control. * Catagories for front page can be, NEW GAMES, POPULAR, CATEGORIES (This can then go into all the sub categories), MYGAMES (for members), * Newsletter so subscribers/memebers can recieve a new daily game or notification. * Links page I will send you the template in PSD format. for more details please PM. Thank You
