PHP Script for Amazon MWS

Amazon Marketplace Web Service (Amazon MWS) I need a PHP script to utilize Amazon MWS. I only need bare functions to perform these features, I do not need a full-fledged GUI. I am looking for an experienced EXPERT in Amazon's MWS API. You must have built applications using this API in the past. All functions/methods should have their required inputs clearly stated and explained. This will be done for multiple amazon sellers and I will be the developer on the credentials. So will need method to pass variables of credentials for seller account and developer account to authenticate. All results should be returned in XML or Arrays Needs to be able to do the following with these API's Feeds API - Create / update product listings including images, prices, descriptions, category, product type etc - litsing can have variations, variations should be grouped as variation_sets and variations - update quantity - Remove products. - get inventory quantity - update inventory quanitty Orders API - Get open orders and all information - get orders in date range - confirm an order as shipped - partial shipments - void order - refund order - partial refund This PHP class needs to be almost completely self-contained. By that I mean that this class should not be making many calls to outside classes. This class can have a few dependant libraries but then those dependant libraries should not have additional dependants. Also please do not require variables on the construct functions. If this does not make sense I can clarify but this should not be a difficult request. I also need a very simple html file which would function as a form to input a new product. The form needs to update with the required feilds for each different category. Also showing optional fields but clearly stating which are required. Use Jquery for the updating of the fields.
