Restrict posting in certain categories by user role?

Hi there,
I have a site using buddypress, and paid membership pro. I’d like to have two user types— free, and business (which would have a small monthly fee).

I’d like to set it up as custom user types, so people on a free account, are assigned the role of “subscriber “, just for example… but business users have slightly higher access..

Instead of using a geo directory addon to charge a fee per listing , is there a way to set it up so there is no fee, but restrict post type/category by role level?

For example, say I have directory categories like “free metups”, which users of any role type can post in…. these include events which would be free for the public to attend.

Then say I have a category called “special events”, which features events which have an admission fee to attend. Since I dont want free users posting these events, which would potentially bring them revenue, I want to limit that category to only business users can post. Anyone can read and comment. But only paid business users can publish them.

Is this possible?

Thanks!
Cass
