Since you seem to have both time and patience, just start over and give this a try:
Stop your dog from pulling on the leash video - YouTube
It will do no harm and might be all you need? If it fails then hire a trainer.
That video is really helpful, thanks. I do something similar, with the turn every time he gets ahead of me, and he will do good with that. It's just maybe I'm not doing it enough. I'll keep on it, and try some of the other points in the video. Thanks for the link.
