Look into a business networking group called BNI and see if they're in your area. If there isn't already a mortgage broker in the local network, he'd be a candidate to join. BNI's website can give you the details about the group so yu can see if it might be a good fit for him. Also encourage him to join the local Chamber of Commerce if he isn't already a member. They have a lot of networking activities.
Good luck!
