Buy and Sell script & design

I'm looking to make a script on PHP to allow users to buy and sell video games and games accessories. features: -Easy admin control panel -email system between members -users can buy and sell at any time -easy attractive design -rating system for sellers (option available once a buyer buy the item from the seller) -seller can add pictures, notes about the game he is selling -payment system going to be by paying the seller direct by paypal or cash or wire transfer.*seller chose what option to show. -search engine for products available in the webiste -category browsing. - integrate google ads to the design -premium items selling (Users can pay small amount by paypal or credi card so they can list items on feature items on main pagel) it is similar to posting a project here to. - any other idea suggested by designer would be much appreciated. the website is for selling and buying video games and video games accessories, not looking to make money from it only from premium items and from google ads at this moment Please create an account on [login to view URL] and see how they buy and sell items, looking for something similar. design should look something very simple and clean similar to [login to view URL] or [login to view URL] Finally, I need to see similar projects and designs. small example attached for one of the option we looking for. budget can be little more fixable, depends on your designs and work. PLEASE check your portfolio, I have noticed many people sending me websites claiming they did and to finally find a footer made by someone else, these companies or people will be eliminated
