I`m just wondering if there is a hosting company that does the billing for you with order form and everything?

More of an affiliate type arrangement? Really, I think you are better off with something more along the lines of instabill/revecom for this and not letting the host control every aspect of your business. What if you want to move to another host? Boy, *that* would be nearly impossible.

Yes, you`re probably right. I`ll stick with my host and instabill.

Alabanza essentially offers what you are looking for. But their expensive, and like Chicken said, it would be very difficult to leave.
