marketpress tutorial in a multisite network

Hello, I would like to see a complete tutorial ( or any help ) to setup an ecommerce platform with premium features.
This is my business model:
All sites in the network is a shop
Formule 1: Free ( a ad will be displayed )
Formule 2: No ad
Formule 3: Payment Gateway
Formule 4: Own Domain
Formule 5: Free with revenue sharing

Thx
@PC
