Creating Choice of On Off or Recurring Billing Form Membership Sign Up

Hi,

I am wondering how I can go about setting up a payment system so that when people go to register for my membership that can either pay by a one off payment or by a recurring payment.

Inside the membership pro payment options you have four options such as recurring, one off, one off the cancels at end date etc

I just want to be able to have it so that people purchasing my memberships can either pay a cheaper fee for making a once of fee or pay slightly more one payment per month over a few months.

I don't mind of O have to hook up Woo or gravity or my 1 shopping cart account etc, but how can I go about this?

Thanks for your help,

Johnathon
