Import/Export Information from one site to another

An account has been created for a company which allows the member to create their own store selling their products. However, it does not allow for much more. What I would like to do is create a website where we would have complete control over the design, programming, seo, etc. I have already uploaded & installed a shopping cart (vp-asp) on the new server. What I would like to do is pull the product information (photo, cost, item info, etc.) from the merchant cart, and place the information at the new server. Then we would also need to send the orders that have been placed from our server to the merchant server. Can you do it? Budget is negoitable, but can't exceed $200.
