Amazon MWS, AWS expert required for exciting project

Hello, We are looking for an experienced and knowledgeable individual who has vast knowledge of Amazon MWS and AWS and pays close attention to detail. We are looking for a tool to help with Amazon product research. The tool will need to be subscriber based as we plan to offer this to other users on a subscription basis. The work flow of the tool: 1. The tool needs to scan the 5 European Amazon Marketplaces. 2. Compare prices and bring back the results of the products with the lowest prices. 3. It needs to show the Amazon Rank, Profit, Category, Est Sales, ROI%, FBA Fees. 4. The results will then be shown against the UK Market – For example The software scans the market places finds a product which sells for £10 in the UK and the same product in Germany for £3. 5. The software needs to be running constantly searching for potential deals and updating every hour. 6. The software needs to be linked into Keepa so the user can hover over the item to see the product history. 7. Currency Exchange to be calculated in results 8. The ability to change the results Market place so for example you may want to find products to sell in the German market, so you would look for offers in the other ones. Naturally when the tool is working out the profit it will need to all be in £ (GBP) using this calculator integrated into the tool -[login to view URL] Please ensure you will be willing to help me with any queries and adjustments to the tool for 1 month, 30 days after the completion of the tool.
