Amazon Custom Software Needed

Hello, My company needs a custom made Amazon software program. We are sellers on [login to view URL] and we need a tool that interacts with [login to view URL] via a desktop application. The program needs to be able to check and compare prices of a batch of items, upload/download inventory, download and manage orders and a few more specific functions. A similar program called SellerEngine ([login to view URL]) already exists, but it does not fulfill our particular needs. Nevertheless, check it out as a reference because what we need would be something similar. We would like a programmer that preferably has had some experience with Amazon Web Services and VBA are required for the, but I assume you may need more to successfully complete the project. I need this done relatively soon. Although quality of work is more important than the time frame, I would like to have the project completed as soon as possible. Keep in mind that if you are not familiar with AWS (Amazon Web Services) All data must be stored or uploaded from an access-database. Please contact me if you have any questions. I am looking to work with reputable and honest people. Serious bids only please.
