Allow Users to Import Ebay Auctions into another auction site - repost

Need a programmer that knows Ebays API and PHP. Put simply I need a script that will allow user's to import their auctions from ebay to my auction site and fill in the title, description, pictures, and other fields. -Need something similar to [login to view URL] (top left corner hover over sell on Bonanza than click Import from Ebay) - I do like Bonanza layout. I would like users to put in their own percent mark down -Would also like all of a users feedback to be imported. Not sure how big of a project this would be. Let me know what you think. Also will need a programer to make an app for phone to allow people to sell/bid thru phone. thanks
