Stanza

Hi guys,
 
I'm in the process of developing a couple of websites for clients who only promote their products/services to trade customers. I need to figure out the best way to protect specific pages (and custom post types!) from visitors unless they're signed in as "trade members." I need the ability to redirect them to a trade member registration page if not logged in or registered, and then also need the ability to manually approve them.
 
There seem to be solid plugins for restricting content, but not ones that also handle the user registration side of things. WP-Members looked ok, but then it doesn't appear to support custom post types
