Self & premium serve sites on one install?

I’d love to setup a site where I can do both self-serve and premium sites on one install. What I’m thinking is two levels of DIY (with different plugins, themes, storage, etc) then three levels of full-service paid packages. I’m planning on doing the full service sites via either MarketPress or WooCommerce, but I’d rather not have people getting setup on a paid DIY plan seeing the option for the higher levels. Maybe this isn’t the right plugin.

Basically, what I want:

Level 1: very basic, as automated as possible, paid

Level 2: a little more advanced, as automated as possible, paid (more)

Level 3: basic custom package, payment is automated, but I handle site setup on the back-end

Level 4: Like level 3, but with a few more plugins

Level 5: Like Level 4, but with a few more plugins

Suggestions?
