Amazon automation system using MWS API

I need a simple Amazon marketplace automation system with the following requirements: - it has to be created in php - it must be able to run in xammp and on an apache server if i wish to upload any scripts on to a server - it must be created with amazon's marketplace web service (mws) - [login to view URL] - I do not mind if some parts of it are created using scraping methods the application must have the following functions: - addListing($isbn, $price, $quantity, $condition) : This function should allow me to insert books into my inventory - closeListing($isbn) : This function should allow me to close a listing in my inventory, if it finds a book with the same isbn the listing should be closed and true should be returned - changeBookPrice($isbn, $price) : This function should allow me to change the price of any book in my inventory - getOrders() : This function should return an array of unshipped orders, with the order number, customers name, delivery address, isbn of the book ordered, quantity, price paid - confirmOrder($order_numer) : This function should change the status of an order from unshipped to shipped. I am under a tight budget so I will be choosing the best price, if there's any questions about this project please contact me.
