Convert FTP files to ebay and Amazon listings

I sell books online. I have an FTP file which is updated daily and contains information on all the books available for sale from a UK book distributor. There are about 500,000 book titles in this FTP file and it contains information such as price, title, picture, date of publication etc. I want to take this FTP information and convert it to list it on eBay in CSV file format. Once a book has sold, I need to take the buyer's details including address and upload these to back to the distributor by FTP. I can provide examples of these files if necessary. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
