Well in the North Lincs (Wolds) area I would say you would find no better than Rory Major (Bryantscroft) - he has been successful with HPRs, Setters, Spaniels and Labs.
As a trainer he is exactly what you are looking for - he will train you to train your dog, he is reasonably priced because you get value for money with your training sessions.
Just my opinion but speaking from my own experience.
