I would be happy to recommend Ronnie Rose, at Eskdalemuir. I took Level one in 2003 after 27 years stalking without, as I did not and still do not believe in compulsory examination. I thought I would not learn much. How wrong I was. A friend who did the course with me and who had stalked for 20 years, felt the same. Ronnie was also the least expensive at the time. Check out his website.
