Restrict wp-admin access to paid users only

Hi

I wanted to ask a quick question about your members plugin to help me understand if its the right plugin for me please :)

I’m looking to have a membership plugin which will allow me to restrict access to certain parts of the wp-admin area only to people who have successfully paid.

So for example.
* A visitor would be able to register on the site (as a contributor role).
* Once registered (or at the same time) they would be prompted to pay for a subscription.
* Once they have paid, they would then be able to access the Posts and some CustomPostTypes within the wp-admin
* They would be able to continue to access the Posts and CustomPostTypes so long as they have an active paid subscription
* If their subscription expires/ or they fail to have an a​​ctive subscription, they wouldn’t be able to access the Posts and CustomPostTypes from the wp-admin area until they have paid.

Ideally I would like to handle the payments via Paypal subscriptions.

I hope this makes some sort of sense and wondered if your plugin would be suitable and can help do the above?

Thanks
