Let me promise you from painful, firsthand experience: Free agility training from someone who hasn't really learned the art can ruin your dog.
I had a boxer and I wanted to do agility in the worst way. I had NO CLUE about the sport and no clue about competitive obedience or anything. I signed up with a local woman who was actively running her dogs. She would super-soak dogs for barking (This I would not allow on my dog) but she would also force my dog into the tunnel and over the obstacles. My dog had no choices in the matter. But the 3rd week, she would stress so badly on the course that she couldn't be off lead at all. Because I started agility with the sole purpose of having fun with my dog, I quit. Later, when I knew better and tried a different approach, my old and sensitive boxer eyed all of it with grave suspicion and held her ground until I just let it go.
Find someone who really knows what they are doing. Attending some lessons isn't enough. Agility takes a few years to really learn.
