Product Comparison Website

I require a product comparison website to be built, it will only feature one type of product so its not very complex. The website will be database driven, the product information will be uploaded to the website via datafeeds (CSV files) from different retailers, which will need to be imported into the database and queries will then be setup. The website will also require a search page which will search the database for various different queries. If you wish to apply please send me a list of previous websites you have created and also a estimate of how much this project will cost. Thank you.
