Want to create a custom site on multisite for new users

Ok so I am building a membership site for a team and when they get a new team member and they sign up I would like to be able to give them a copy of the main site. The main site you can see here TheMultiplierSystem.com. But when a new member signs up for the free membership I would like it to be the same site except be TheMultiplierSystem.com/JohnDoe. Is this possible? To have all the same content I realize we will have to do some adjusting to the links and autoresponders but would like it to bring over all the info from the main site. I think Cloner will work for this but that is manual is there any way to automate it?
