Cloning Demo Site to Another Site

I'm wondering if this would be the best option to use, since I'm new to the multi-site.

I created a demo page for the visitors to view and and sign-up with WPMU Pro Sites to have their own site. What I wanted to achieve is copying over everything to their site and of course I would have to edit all the "yourdomain.com/#" urls to be that awesome support guy . Just didn't know with the levels if this would cause an issue.

Not a big issue really, since I figure it would roughly take me 1-2 hours to copy over everything manually and make sure all the settings were right.
