Amazon MWS Management Scripts

We are seeking a php/mysql programmer who has experience with Amazon MWS. We require a few programs to be written in order to help maintain our inventory. These programs include check current inventory, check prices, update prices and stock, amazon search query script, and a basic script to ping the system when an order is received. These applications are straight forward and we can provide complete details so there is no guessing at what you have to do. You must be able to produce the applications quickly and the programming should be kept clean. The web interface will be basic, no fancy colors, just white background black text and normal links.
