Bulk Upload of Products to Amazon Seller Central via .XLS & API

We are a retail watch, jewellery and gift ware store. We are looking to start selling products on Amazon''s Australian Market Place. We have setup a Seller account and have been approved to sell several of the brands we currently sell. We are also approved by Amazon to develop our own version of an app. We are looking for an experienced developer who has worked on Amazon bulk products uploads via [login to view URL] document templates provided by Amazon. Our store uses an inventory management / POS system called Retail Edge. Retail Edge has an API solution called eWeb. The eWeb services is well documented and a copy of their documentation is attached. We also have a Shopify website. The successful contractor for this project should be familiar with the Amazon Seller Central Marketplace, Amazon's Departments, Amazon's product uploads templates and also Amazon's SP-API. The first stage of development will involve configuration of a single department - we have selected Clothing, Shoes & Accessories > Women > Jewellery > Necklaces. A copy of the Amazon XLS template for this project is attached. The scope of the project is to capture details of products which have been configured in Retail Edge to be sold on Amazon. The relevant fields then need to be populated in the Excel spreadsheet then the spreadsheet submitted to Amazon via the API. Upon successful completion of the Necklace template, if both parties are willing to proceed further, then subsequent projects will be awarded for other departments and enhanced functionality such as inventory synchronization.
