Adding Bulk loader application to Auction Website

I'm looking for someone to create a Bulk loader for my auction site. This bulkloader will need to be available to registered users of my auction site to be able to list several products at once. My site is in PHP with MySQL database. My website for reference is [login to view URL] this is the site the application needs to be compatible for! To recap: I have a auction site and currently registered users can list products to auction, however currently my website allows users to list products 1 product at a time. I want a application that will allow users to list multiple items at a time then click submit or load auctions which will send the information to a table within my database. I want something like ebays turbo lister. but one built for use with my website. Checkout ebays turbo lister here: [login to view URL] to get a understanding what I'm looking for and advise if your able to create something like it that will work for my site. Please post your lowest possible bid!
