Build a Website with FB Authentication and Groups API

I'm looking to build a website with facebook integration functionality. Specifically to the business pages and groups. It needs to: - Integrate with Facebook Groups & Pages - Allow for photo upload to groups - Allow for photo removal from groups - Post photos to pages - Keep track of Inventory (Sold, Listed, Unlisted, Shipped) - Create unique ID#s for each item of inventory - Upload files for local storage - Schedule out post uploads - Keep accounting records (when item is marked "sold" the gross profit is calculated)
