ASP/ Ebay API job

Skills required - web programming (classic ASP) and Ebay's Trading API. I need an interface to Ebay's Trading API that will allow me to 1) list an item for sale on Ebay and [login to view URL] using AddItem method and 2) update quantity for an existing listing using ReviseItem. I need 1) interface and 2) sample code that invokes it. No GUI is needed, I'll be plugging the scripts into an existing website. The code should be classic ASP using vbScript and should use no outside components. No server-side jScript either, not supported by the server. More functionality is expected to be added in the future, so any reusable code should be encapsulated. AddItem documentation is at [login to view URL] The interface has to support all required and some of the optional parameters for AddItem method.
