Amazon Marketplace API

I am looking for an experienced Amazon MWS API programmer. I am building a PHP / MYSQL application which will integrate with Amazon MWS API. I would like a script / class which would allow me to do the following: Create / update product listings including images, prices, descriptions, category, product type etc Update Amazon with our inventory numbers Download orders with all the detail including items sold, shipping requirements (standard, expedited, etc) Mark an order as dispatched Mark an order as cancelled We have an existing order system and I would be integrating your code / library into this so that I can just call your functions to do a specific action. If you have this code and are capable of doing this project, please send me a message. I would be grateful if you could send me a small code snippet to show you coding style and an example process. I will contact you back with a simple question or two to test your knowledge of the API. Thanks, James
