Membership 2 & Pro Sites Question

Hello,

I'm trying to set up my Membership 2 and Pro Sites Plugins, however, have questions. I'm trying to set up an up front fee for pro sites, plus an ongoing support/maintenance fee. Does that make sense?

i.e. - $XXX.XX amount to set up their account and an ongoing $XX.XX/mo to support and maintain their site.

Is this something I can do with either Pro Sites or Membership 2. The idea is to have their pro site make a monthly payment after their initial payment, if not be rolled back to the free version of their site.

Hope this makes sense. Please advice ya'll,

Thank You,
