Custom Subscription Pricing or Bundling

Site URL: https://www.natuswellness.com

Hello,

We are trying to setup a subscription that requires an additional up-front fee for the first installment. I know this is possible in Stripe, but I dont see how this is possible in Squarespace Advanced Commerce. To illustrate what we are trying to do:

- Month 1 = $200 (regular price of $100 + an additional $100 for an initial consultation)

- Month 2 through X = $100

Another option would be to bundle two products and only offer the bundle:

- Product 1 = $100 for an initial consultation (1 time charge)

- Product 2 = $100 recurring monthly payment (subscription)

Are either of the above possible? 

If not, is there a plugin that works?

We want to avoid custom dev work with Stripe due to the costs. 

Thanks
