paid membership extension for joomla 3.x

what extension can i use in creating a paid membership site, were a person invites a certain number of persona and each of these persons refers the same number of persons and so on...till the chain breaks eventually.
e.g


I need an extension for this please...

Hi

I am sorry but Membership Pro could not be used for this requirement. You will need to find a different extension in this case.

what other extension can you suggest for me...

Hi

As far as I can see, no available membership extensions could be used for this requirement. So I think you might have to hire someone to develop a custom extensions for you .

Sorry I don't know anyone. Maybe you can try to contact developer of other membership extensions and ask them to see whether they can build it for you!
