I want to use membership+ to create a specific registration flow for my customers

I want to create a specific registration flow to capture/squeeze all members into a free registration page, then, once they’re registered as standard members, they’ll have access to pay per view content, or, be presented with the option to become a premium member/subscribe.

Standard registration > Welcome page

Welcome page> Option 1 (buy product) or Option 2 (Premium subscription)

If they click Option 1, they’ll be taken through a standard intake form to book an appointment and pay for the product.

If they click Option 2, they’ll be through the standard subscription process to access premium, protected content.

Any insight as to how I could go about setting this up using membership+?

Thank you in advance!
