Extra modules for resellers, licenses etc..

is it possible to make reseller account, what can add users and with the license plugin to select from a pool of 100 license, what only the admin can create, one license to a user?

for this i need to buy the e-commerce platform. I dont see it in the shop.

so i need beside the current license i have:

1) license plugin

2) ecommerce plugin.

3) anything i miss!!

we dont have front page, just a cms to controle all. Will you plugin work for us.

I wait 1 week to get the right answers!!!!!!!!
