I know this gets asked a lot but asking anyway

I am interested to learn what scripts are out there for powering a free hosting site on a whm/cpanel server.

The idea is to create automated free subdomain accounts via whm under either one or several domain names with header and/or footer adverts inserted, the subdomains thus having their own cpanel.

I had hoped to do this with either WHM, AWBS or WhoisCart but none of those are ideal for this specific purpose currently.

Any suggestions?
