Pro Sites Plugin – Different Questions


i have some Problems in understanding the Pro Sites Plugin. I set up a wordpress multisite (subdomain), created my theme, my content and now i like to do the following:

1. Visitor comes to my page

2. Visitor likes it and wants to get a subdomain with the same content

3. Visitor go to checkout page (register-page?)

4. Visitor has to fill in some fields (how can i define the fields?)

5. Visitor choose subscription plan(is there the possibility to change the appearance?)

6. Visitor checks out and pay over paypal

7. After receiving the money i want to unlock the new blog

is it all possible to do withthe pro sites plugin?

Best Regards
