Virtuemart + subscription + CB

[acote]

Hello

at first please excuse my english.

I have a few questions about VM. I would like to hire some products from my shop. Now I dont`t know if it`s possible to realize such a solution.

What I need to realize is:
ABO 1:
There will be a free membership which (trial version 30 days) the user can choose a max. of 3 products (low products and high products)

ABO 2:
There will be a payd membership which the user can choose a max. of 3 products (low products)

ABO 3:
There will be a payd membership which the user can choose a max. of 3 products (2 low products and 1 high product)

ABO 4:
There will be a payd membership which the user can choose a max. of 3 products (1 low products and 2 high product)

at all the membership it can possible to have more transport options.

Now it`s the question if somebody knows a good subscriptions system and if i need cb?

am grateful for every tip

kind regards
max
