I'm setting up something the same way at them moment. Haven't really looked into a solution yet. Interested to see what people have to say as I was considering just locking the forum and manually creating the memberships to the forum. However this could be a pain in the ass to do daily if the site begins to do volume. We're set up for cc billing already on the project, but I'd like to see a way this can all be managed automatically via vbulletin myself...
Hope someone responds
