Membership - custom offline payment method

Hello, I would like to know if Membership Plugin offers an offline payment method to the users of my site.

It's a closed community and I know for sure that many of them doesn't have PayPal or any other online payment service (we're in Italy).
The ideal service would be:
1. the user choose the offline payment method.
2. the system notify the admin about the offline payment and put the user in stand-by.
3. as soon as the payment is done (check to be done outside of our system) the admin will approve the membership request.

Thank you in advance.
Andrea
