Clone Affiliate Store Using inventory from Multiple Stores

I am creating an affiliate website to sell chairs. I will be basing it on the website chairs dot com with one key exception. Chairs dot com uses inventory from one network - Yahoo Shopping using XML feeds whereas my store will carry inventory from Walmart dot com Overstock dot com Target dot com Amazon dot com Yahoo Shopping Costco dot com (if available) Additional functionality over chairs dot is 1) ability to sort order by product rating, clicks / views. 2) Wordpress blog under a subdomain skinned to match the website Images and logo will be provided by me to replace the ones on chairs dot com. Links to stores must contain my affiliate ids for each store which will be provided after a prototype has been produced as the last milestone. You must have prior experience and provide me with examples of stores you have built or be able to detail to me how you will go about building the store in your response. Responses not conting this information will NOT be selected. I am a very fair person to work for and have several projects I want to partner on. So please consider this in your reponse.
