Merge multiple datafeeds to create one and upload

Hello I need someone to merge multiple datafeeds to create one main feed. Then quickly upload main feed to my shopping cart. I need products with images merged, category and subcategory, and manufacturer name. It is mainly easy except the product image datafeed might have one product listed five separate times because theres five different images so its not already combined for you. To do a vlookup, etc will be difficult with duplicates. To make matters easier, i dont need ALL the different images to one product, just one image is good. So just pick first image. I can give you further instructions once you accept, but it does involve cleaning up files, etc to properly merge everything together. You can also parse identical websites from my supplier to help you grab the category and subcategory. The datafeed contains 19K products.
