Does anybody know of a full module for a members area that can offer a Subscription service, with an admin section to administer it?

This would be really great feature with in zen cart!!

I would look into making one but i am a bit of a newbie with PHP.

I also would love to find a module that would use a calendar and booking service with that members area??

Or should i be talking to a developer?? lol

If it was easy enough to get the hang of i would have a go, but get confused with the PHP.
