Pricing structure setup for Pro Sites/WHMCS plugins

I would like to know if these pricing structure scenarios are possible.

1. Sign Up for membership, the initial price is $1,500 and then the customer is automatically billed $50/mo.

2. Sign up for monthly membership $50/mo, during the sign-up process, there's an 1 time upsell product for $1,500.

Are these possible with Pro Sites / WHMCS combination?
