PHP Pro Bid Modification

I am using PHP Pro Bid and a modification to Import Ebay Listings. I need a modification creating like used on [login to view URL] for users that have a store with me and a store on Ebay. (yes I know thats different software but ending the auctions on ebay will be the same function) They advertise the following : Quote : "Currently have fixed price or store items listed on ebay? Then you can easily import your existing items from ebay to bidStart! All you need to do is fill out the form below. We can even automatically add new items you list on ebay to your bidStart store, as well as remove items from your bidStart store when they sell or end on ebay, and remove items sold on bidStart from ebay! Note: Auction items can not be imported. " This is what I need on my auction website. I already have the import mod , its the extra part of ending an auction on my website for store users if it sells on Ebay and ending an item on Ebay if my store sells it. This is for Buy it Now auctions only and for store users only. If you can complete this I also have other work such as creating a bulk lister software for PHP PRO BID. Please don't bid above $75.00. Thank you and we look forward to working with someone. We will have a lot more work available if we can find the right person to work for.
