I need a module to output eBay sold items to my hosted MySQL database (invetory only)

I'm looking for someone to use the EBay API and when an item is sold to adjust the quantity stored in my MySQL data base. All I am looking for is an inventory adjustment; no other records are needed to be recorded. I presently have a module/system which loads and drops the EBay listings based on this inventory stored in my shopping cart software so I am looking to close my inventory loop. Below is the overview of your module needing this connection - ShopSite MySQL DB Module: Have you ever wished you that could access ShopSite page and product fields via MySQL using PHP or Perl? With our new ShopSite MySQL DB Module... now you can! This free add-on module syncs the ShopSite SQLite database to a separate MySQL database. Merchants can then easily use PHP or Perl to access any page, product, or setting in ShopSite through the MySQL database. Features include: • Configurable setting for how often the MySQL database is synced • Simple PHP functions and classes to access any page or product field • Advanced PHP classes for loading an entire product or page • Examples of how to output page and product data Uses for this module could include: • Displaying real-time inventory via php • Dynamic price and name for Order Anywhere pages • Hiding add to cart buttons based on inventory levels • Displaying savings based on sale price vs. regular price • Dynamic breadcrumb navigation PHP developers and programmers can access this data in a variety of ways for truly custom and dynamic pages and features. The module combines the stability and power of ShopSite with the dynamic features of PHP Overview: The MySQL database module integrates seamlessly with ShopSite, making it easy for merchants to access any product or page information via MySQL. ShopSite’s internal database is not easily accessed by developers, making it more difficult for custom, dynamic applications. This module synchronizes the ShopSite database to an external MySQL database. Merchants and developers are now free to use a dynamic programming language like PHP to access any ShopSite product data easily by querying the synched MySQL database. “ShopSite is a great, feature packed e-commerce application, but some merchants are looking for simple ways to access and display dynamic content in customized formats,” says Robert Mangiafico, CTO of LexiConn. “With our new module and easy to use PHP functions and classes, developers can simply add a few lines of code for dynamic features such as real-time product removal based on inventory or ‘on-the-fly’ navigation based on click path.” REF: LexiConn Knowledgebase :: MySQL
