AMAZON UPC CODES AND BULK LISTING TO AMAZON

I am looking for someone WITH DEEP EBAY & AMAZON EXPERIENCE to add my products to amazon. They will have a generic description, I will need SKU's added, description, price and image. Need 5000, but will start with project of 100-200 UPC Codes to create listing on amazon.com. Must have experience with amazon datafeed creating new items with UPC, Images, Product Details, Keywords, and listing header. We will give you a few examples from a few sellers listing the same type of items. Basically, you are copying items (bundles) listed on amazon from the sellers and specific listings I will give you, then creating variations in product image, details, and header to the datafeed so we can upload to Amazon. Each listing must have a new unique UPC to list on Amazon. Let me know what ideas you have or if you have similiar experience. We will upload our product feed to Amazon. If the codes pass amazon's system, we would pay you. If some codes can't pass, you need to replace the UPC codes by qualified UPCs Show me some projects you have done before which had similar requirements
