XML FEED OSC COMMERCE

I require a feed management system for import and export to other oscommerce sites. The incomming feeds will be from various sources including xml and txt tab delimited and possibly csv files. The out going feed will be available from an oscomerce solution supplied by me. this will update the customers site depending on which feed or feeds they have subscribed to. Both solutions will require the ability to switch on and off parts of the feeds from an admin/ configuration point and the ability to adjust margins/ based on cost prices by either fixed amounts or % Think thats the basics if anyone needs a little more info then please ask me specific questions, I will do my best to describe my needs ## Deliverables 1. all product related information such as but not limited to? rrp, price, and cost price, manufacturer, name, model, description to be transfered 2. the customer will have an easy configuartion interface that will allow them to mark various aspects of the feed inactive (such as and not limited to the name or description which they may change for seo work) 3. The ability to import the feed with mark ups as either a percentage for the over product group or fixed amount 4. the images to be imported as sequentially numbered files as they appear in the database order, and not with original product file names as these can be very long 5,. the ability for us to add extra feeds (import) them for any of the file formats they may be provided in, some feeds may be in the form of products and categories and we need to be able to match them up. This consists of the main aspects required and before any work is done we can provide some of the file formats we recive our feeds in to help you create a project? plan
