my suggestion is to go to the club for this. If you go to a pet trainer you will get bad habits, Even competition OB classes are geared for AKC and again they teach it different. Go to the club and they will help you get started the with way.
I can't stress enough how important it is to get into Sch when the dog is young before you mess it up
this goes for anyone who wants to do this sport. The older they are they harder time they have with the sport. I start the puppies as young as 10 weeks going to training. They sit and watch the other dogs and start OB very young. We also start building prey drive and play drive without this doing the sport is nearly impossible.
