Looking for a plugin that will allow only one blog

Looking for a plugin that will allow only one blog on multisite and not affect all other sites...to have registration, and they pay for access to page content on that blog. Can set special password per person and have auto renewal with link to payment gateway (paypal).
Membership didnt give us that. It affected our "password protected blogs by making them OPEN access and we give our followers special password to acces using PRIVACY plugin. Feel free to email me at info@paperphenomenon.com
