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

Specs: The user is an online merchant, selling with ebay, Amazon and e-junkie. The user processes data with MS Access tables, forms, macros, queries, reports... 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 VBA MS Access developer to modify the attached mockup database and populate the API Access macros. the Access macro code can be made using a language such as “.net”. 1. the 2 macros called: • "macro_API_import_from_order_source_data_amazon", • “macro_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 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 provded by the order source API, even if they are not currently included in the tables. [login to view URL] a macro called "API_macro_validate_shipping_address_with_USPS", that would update the "yes/no" data-type field "tbl_order.hold_invalid_adrs" to "True", only if customer's ship-to address is 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 a macro called " macro_API_fulfilled_by_amazon", that uses an API to populate the table " tbl_fulfilled_by_amazon" with all of the available fields offered 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.
