Need a new price comparison website

I need a web designer & developer who can make a easy to navigate price comparison portal where I will display the clothing, electronic items, shoes, lingerie, sex toys, mobile phones, etc deals (updated daily) via product datafeeds in .csv and .xml format. I would also like to make a user login panel in it so that we can offer more specific deals with enticing offers to the registered members. Bidders are request to bid only after thoroughly going through my project detail and who have got the experience with proof.
