In need of a LUA Addon Developer for the videogame, "World of Warcraft"

This game uses an API architect to interface with LUA. I'm looking to make modifications to an already-existing Addon. It will need to have a similar function to another Addon, so integrating that process should be fairly straight-forward. Your task will be to add a repetitive search function to a shopping tool used to browse the in-game trading system. Please, only respond if you're familiar with the game and LUA.
