Members sign up for $x today, automatically billed $yy.yy every 90 days

I'm looking to integrate MarketPress with Members, Supporter, or both.

The visitor has an option to purchase 4 regular products and option for a "special product".

The "Special Product" is a one-time fee (charge immediately) of $9.95. The user is then billed automatically for $69.95 each and every 90 days after the initial purchase date. Ideally, this would also be supported with merchant.

Any leads on how this is possible? Thanks.
