API to integrate USPS, Ebay and Amazon with MS Access - repost 3

Specs: The user is an online merchant, selling with ebay, Amazon. The user will process data with MS Access desktop apps that runs, forms, macros, queries, reports, that link to MySQL tables on his hosted web server... The user ships most product with USPS (USA Postal), integrating with [login to view URL] as the portal to batch export/import the shipping data i.e. shipping address, tracking# and to also print postage stamps and shipping labels. I need a developer to modify the attached mockup database and replace the MS Access tables and empty macros with MYSQL tables/API code that would be hosted on our web server. 1. there would be two API’s called: • "API_import_from_order_source_data_amazon", • "API_import_from_order_source_data_ebay" would run an API to import new customer-order data from the order sources Ebay and Amazon . The order data would be appended to the tables, "tbl_ebay", and "tbl_amazon" (the user already runs a pre-developed MS Access macro to append the new order data to "tbl_ order" and "tbl_orderline" tables, so making such a macro to append to the order and order line tables is NOT in your specs). the existing order source tables "tbl_ebay", and "tbl_amazon" must be modified in order to include all available API fields that are provided by the order source API, even if they are not currently included in the mockup tables. [login to view URL] a n API called "API_ _validate_shipping_address_with_USPS", that would update the Boolean "yes/no" data-type field "tbl_order.hold_invalid_adrs" to "True", only if ship-to address fields in "tbl_order" are identified as invalid by [login to view URL]'s address validation API. This is required because very often the customers don't supply a correct shipping address and [login to view URL] rejects the shipment if the address is invalid....

The user also sometimes uses Amazon's "Fulfilled By Amazon" ("FBA" service) as a distribution center to warehouse and ship some of his product ( FYI [login to view URL]) and needs to run an API to inform him of FBA related data e.g. "Quantity-on-hand" in the Amazon Fulfillment Center, in order to monitor the stock level... Make an API called "API_fulfilled_by_amazon", that uses an API to populate the table " tbl_fulfilled_by_amazon" with all of the available fields available in Amazon's FBA API . I am easy to work with and am hoping to find a reliable full time MS Access/VBA/Web developer for multiple projects.
