Bulk eBay Inventory - Convert CSV into usable eBay template for Selling Manager Pro

We are searching for competent and very experienced professional to customize our CSV file for bulk uploading of Inventory and adding Item Listings to eBay website through File Exchange and Selling Manager Pro. We already have an CSV inventory file with the first 1000 items ready to go, so you will need to have a comprehensive understanding of the requirements for the eBay templates and how to reformat and load our CSV into the eBay templates. When the job is complete, my partner and I should be able to easily upload items into our store in bulk, as well as manage and upload inventory on our eBay store. You must be able to show examples of your work that is currently live and demonstrate your expertise with eBay File Exchange and Selling Manager Pro. Only professionals with significant and positive feedback with this specific type of work will be considered. Completed CSV Files must be uploaded by us and accepted as technically correct or project will not be considered complete until it is. If successfully executed we will will need this done on a ongoing basis. Your understanding of both eBay & Amazon bulk uploading will be a major PLUS!! Any reasonable offers and advice will be accepted. We appreciate your time and look forward to hearing from you soon.
