Build a price comparison website

I need a website for price comparison. for better guidance, please refer to pricegrabberdotcom, hotlinedotua, and pricecheckdotcomdotng. Basically website should be simple to use and beautiful (i have strong emphasis on design). I will set up a contest for brand identity from which i will provide logo designs. Also note that after sale support will be more than valuable. lastly, i will provide most of the needed texts. Lastly, quality product at reasonable pricing is important to me and not user ratings or badges etc, happy bidding!
