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
