fisamo I agree, hard work will be required just like in reselling web hosting. My angle is to approach my web hosting clients.

Early on Tim told me that offering to business would be fine as long as you can pay the bills and they don't blow it up. (Tim is this still correct?)

Anyone seriously interested should, in my opinion, talk to an accountant and or attorney. I got into some serious trouble with the state comptroller over not taxing for web hosting, web design, and computer repair. Now I have a snazzy certificate to hang on my wall and a quarterly report to file.

For billing one might be able to use WHMCS and it's API to handle billing...
