Cre loaded B2B local taxes by zip

I need a module/addon that will allow me to charge taxes based on the zip code within a specific state. In the state of NY the tax I have to charge is different based on what zip code the person is shipping the product to. Please tell me someone has already developed this and I can just buy the code at this point. I need this right away so please respond as soon as possible. I have worked quite extensively with cre loaded but now do not have the time to develop this myself from scratch.
