BuddyPress Profiles Manager is a plugin by Elgunvo that acts as a go between for s2Member (or similar) and buddypress and enables you to hide certain profile sections to non-paid/low level members. You can also specify a message to give people on pages where the user can fill in the info but its not visible to the public until they upgrade.
Features:
A simple to use interface for managing profile groups.
Hide/show Profile Catergories
Teaser profiles (where the user can fill out the information but its not viewable to other users)
