Authorize.net Payment Gateway

I need an order payment gateway developed for [login to view URL] AIM method. I already have the order form I just need the script integrated with my site. The script should be able to create username and password after the transaction is approved so the customer could login to members area to access his order. Also be needing a control panel so I could modify/delete users. I would also like for the coder to provide me a tutorial with the step-by-step instructions on how to integrate/develop such a solution, for my future needs.
