Amazon Order Downloader

I am looking to have a solution built that will download amazon orders and display in a list.. unshipped orders can be clicked on to see details as well as modify addresses, as needed. A transmit button will be clicked and post the order data to an existing script. Written in PHP Uses latest Amazon AWS Page1 (Main Page) Lists All Orders in a table with sort on column headers. Listing Options on top of table. Date Range for results and Status (shipped, unshipped) Button to Download orders new orders from amazon - download process will show progresss bar or a status count. Page 2- Order Details Page, shows all info about one order. Has a link to transmit an order. Page 3- Transmit Page - Shows order details info in Input fields Order Number, Name, Address1, Address2, Address3, State (2 digit abbr), City, zip (5 digit). Product Info, etc. Fields can be changed and click SAVE to update info. A second button called transmit will post the data to an external script that transmits the order to the wholesaler (already developed) that post results into a simply Iframe. Once an order is transmitted, it needs to send data back to amazon to show it was shipped, as well as the shipping method chose, etc.. I need someone with amazon seller experience, currently seller central does everything we need it to except post the order data to our EDI/order transmission program. Thanks
