Inventory Loader Script

I'm looking to have someone write a script that will assist me in downloading datafeeds from my dropship suppliers, reformatting them to conform to amazon's template and upload the feeds as an inventory loader file to my amazon account. Experience with Amazon is a MUST This should be a very simple script that should not take much effort at all for the right programmer. Please note, there are multiple suppliers that I deal with and they each have their own formats. Additionally, I will be adding suppliers, so the script would need to be adaptable.
