Mechanical Turk API Interface Software

I need a basic software setup that can manage the mechanical turk API. This software will keep track of all my HITS (assignments for workers to do) and give me additional functions that only the API can handle. If you've used the MTurk before you know that the interface is clunky. Here are a list of things that I will need to be able to do with the software you create. 1. log in and out. 2. create, edit, and delete HITS 3. create qualifications 4. review the work that workers do 5. approve, reject, or respond to work submitted. The project should be fairly simple for someone who has worked with APIs before. The main thing I need the software to be able to do is stop workers from ever doing the same HIT twice. You do this with qualifications. This must work before I accept your work. Since this is a simple project I will be paying $400.
