Marko's got some good suggestions, but beyond that I don't think your behaviorist will mind if you ask him for advice. He may even suggest setting up sessions with his dogs--and if now, I wouldn't hesitate to ask. Be aware, though, that for him it will be a business session and he'll likely charge, but your dog will have the benefit of working with the behaviorist and his border collies...
