Connect Amazon MWS to MySQL database

The project is to create a PHP file (or files) which connects to the Amazon Marketplace Web Service (MWS) Fulfilment by Amazon (FBA) API service and uploads and downloads data to and from a MySQL database with a suitable field structure. This FBA implementation must include inbound shipping, outbound shipping and inventory. The project would suit someone who has worked with MWS before, ideally with FBA using PHP. There are a number of libraries available that make connecting to the API easier and it is expected that one of these will be used in addition to the code provided by Amazon. The table definitions for the MySQL database also need to be created. Ideally these will match the naming convention used by Amazon. This is not a requirement, just a suggestion. A clever coder should be able to use the XML / WDSL and or the classes provided by Amazon and third parties to produce the database structure fairly automatically. Again this is not a requirement, just a suggestion but is likely to save a lot of time. In addition to the fields the API will require we will need a few extra fields to handle update status to and from Amazon. The code will need to be able to handle multiple market places (each with its own key) and distribution centres.
