s2Member or s2Member Pro?

Hi There! I'm on my second website using s2Member and am having trouble trying to figure out best way to set this one up.
We are the providing customization of a product. There are 2 layers of service: Subscription plans (hosting final product) + Initial submission
Question arises with submitting the file for customization. Is there a way to provide a paypal button to pay for a user to access /complete a form and upload a file a controlled number of times? Example is that we need the the Basic level subscribers to only pay for and access/ complete/ submit the form once, a practitioner 2 times and a Pro 3+.
I have looked into ccaps in s2Member but don't quite see how to allow the access to the page with the form only only 1 or 2 times. There's a lot of discussion about s2Member Pro having forms - will that work better?
Thank-you for help/ ideas,
Liza
