Product feed driven website

I am looking to build a marketing website which will aggregate product XML feeds from about 10-15 retail websites' product catalogs. I can also get the feeds in excel but i prefer something dynamic that changes when the merchants change their catalogs. To give you an example of what I am looking to build have a look at [login to view URL] [login to view URL] feeds might be formatted differently and you will have to figure a way to make sure that they all come out with the same look and feel. 2.I want to have a search option that users can search by fields such as designer name, price, product type, products with %discount, free shipping or a combination. [login to view URL] website needs to meet with SEO best practices and include a sitemap for easy spidering. If I am happy with your work I will have more websites for the coder that is chosen.
