Does anyone know of a completley automated system for new sign ups?

ubersmith works but isnt quite there yet. I am looking for when a client comes into the site and signs up for a package (custom bandwidth selection also) that it is created in realtime in IIS as well as my back-end client managmenet system.

I need the backend to take in the package pricing in realtime as it is generated on the fly. Add the user info in the SQL DB so it has somewhere to grab future data about that client. Then on the clients renewal date bill the cc again, if cc authorization is approved then account is ok and an email is sent. If declined then email is auto sent and account is suspennded after 24 hours. (time changeable)

ubersmith says that it will do most of this but right now it is a part auto process and part manual.

Why cant I get it all auto?
