Ebay API and Inventory Management

I need someone to automate the loading of my supplier's inventory file into my MySql database. This project also requires a script that compares the quantity and price of my active ebay listings to the quantity and retailprice found in my database. The productID can be used as a uniquie identifier. Where there is a difference the script has to use the 'reviseitem' API call to update the active listing. My domain is hosted? with a Godaddy reseller. Coder must be familiar with the limitations godaddy places on? inbound and outbound activity on it's servers (Curl, cron, etc)? Requirements: Supplier 1 table (S1T) 1. The file will have to be retrieved daily via a link supplied by supplier? - (Perhaps a cron job) 2. Load file into DB table 3. ReCalculate retail sale amount - Using formula I'll provide Active? Ebay Table (AET) 4. Using ProductID compare new quantity and retailprice? in S1T to quantity & retailprice? in AET. If either value is different use ReviseItem to update Ebay listing. I have 3 or 4 other supplier intergrations? that I'll create a project for in the future.
