25833 freewebs clone?

I have a small hosting company and want to start offering free space like [login to view URL] or something along that line, if you use my free space you have to display advertisements on your pages? are there any affordable solutions out there? I also have a site using a state name and want to offer splash pages for companies located in that state, and want them to be able to log onto their page and make changes and the main page be a sort of business directory linking to the splash pages
