I am interested in setting up a site where people can have access to a certain amount of webspace under my domain name. Where can I look to learn how to set this up, set up their space limit, their templates, etc?

Thank you so much in advance!

Heidi--new and trying to learn as much as I can!

There is quite a few scripts that do this. Check out http://hotscripts.com

You may want to look into using a resseller account.

I Think you need some reseller account with something like WHM and Cpanel as control panel. From their you can sell webspace under your name with independent control panel for each domain.

Yes, a reseller accoutn would be best. Woth a reseller account, your clients will have their own control panel to manage their webspace. With some sybdomain script they wont have that option.

Look for a reseller account with cPanel and Fantastico. Then you have all you need

Since people before me already given you some advice, I will touch on other things. Start reading up on maintaining or running a free webhost on forums.

He said under his domain, so just normal shared hosting package will be fine with unlimited subdomain feature..and script to manage and activate subdomains..

If you are looking to add subdomains, just look grab a decent plan with a dependable host offering a lot of subdomains.

Mind you, if you offer subdomains or setup accounts that are beginning to crunch out resources on the server, it wont be long before your ability to create subdomains gets restricted by your webhosting company.

Be sure to advise him what specifically what kind of sites you plan on having on your subdomain i.e. plain html pages or CPU hungry php sites / scripts / programs
