Build Comparsion website

I need a highly experienced and talented web designer/programmer, has the capacity to build a powerful and attractive price comparison website that enables customers to easily search and compare products/services at competitive prices, with the added option to be directed to the provider to complete the transaction the website must be similar but not a copy to: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] • Site must be compatible with all well known web browsers and must load as quickly as possible. • A full user guide must be included, explaining how the site, database and script work. This must also show how to customise the website, add or edit content, add/remove stores etc. • I need to have copyright ownership of the completed project, history of recent searches made by customers in the site along with a forums page. Admin control required with these minimum features • Affiliate sales, affiliate tracking and link amendments. • Traffic information statistics to our site • I should Receive emails and read all "contact us page" info received within the admin area and able to reply. • Relatively easy for the admin to customise - add, delete, move, content/pages content manages the price comparison website for me. I would like the following to be included: Developed in PHP and MySQL is equiped with: -Product catalog (including featured products) -Product comparison -Product rating and review -Price comparison -Merchant rating and review -Product search -Recent searches -Search engine friendly pages -Price Alerts for visitors -Email a friend feature -Clickthrough tracking and reporting -Automatic thumbnail generation using GD or imagemagick -Auto-Crawler, for crawling merchants' websites to get products and prices (It is useful if a particular merchant dont support datafeeds) -DataFeed Import, for importing products from any affiliate datafeed and automatically creating products -Administrator Area for administrator to manage every feature of site -Shipping and tax calculation based on zipcode -Search within search -Sitemap (HTML/Text formats) also a classifies section for car and homes sales and a jobs section the website must have a section where you can use a website address to pull data from the merchants website e.g. product listings To be qualified you should show us ready make price comparison scripts that you already done WE NEVER PAY IN ADVANCE, HOWEVER ONLY UPON COMPLETION OF THE PROJECT. we'll pay you only after work completed via GAF's escrow. No exceptions. I prefer to have site in php, but if one thinks aspx would be a better/faster option, I'm open to suggestions. the website must be for the UK market Basically what i want is a modified clone of [login to view URL] with added extras to the script
