Im wanting to slowly inch my way into the hosting business. Ideally Id like to offer mainly free hosting with ads on all users sites like geocities, angelfire, tripod, etc and then offer maybe 1-2 paid options to remove those ads.

Id like for users both free and paid to be able to use their own domain name.

Ive got a dedicated server to use for this.

What else do I need? Obviously the software to handle all of this is a major question. Im running cPanel/WHM for the server control stuff.
