Joomla Chicago CMS Group

I need a method to create 400-600 different users their own set of 5 pages each.
It will be their area. They will view it as their own website.
for example: www.our-same-product-line.com/billy and www.our-same-product-line.com/sally.

Each person needs 5 to 6 pages they can edit.

When the customer goes to www.our-same-product-line.com/billy they cannot see other users menu tabs or pages. These pages will be for the salespersons own business.

I only what one instance of joomla installed.

I looked at UHP2 and its too ugly.

I prefer a joomla solution but, not limited.

Time is critical !!! All suggestions welcome.

Let's see, we have 89 Members, each produce 5.4 webpages each, done deal.

We can deliver in 4-6 days, max.

Phil, I'll look into it, seriously.
