My trainer goes 25 minutes to the show barn to give people lessons, plus about 15 min further for others. I pay $45 for an hour private, and the others pay $50-55 if he travels to their barn. He's an amazing trainer though.
I'm lucky enough to only live 7 minutes from the barn I take lessons at. If you're looking for a trainer to come to you, you may want to check local barns. Alot of trainers are willing to travel to obtain more clients.
I pay $55 an hour for my lessons but my 2 instructors are the best. They compete at Nationals (PHAA) and are very good at all aspects of western riding. Plus, one of my instructors used to do dressage. I think I get very good value for money because I learn a lot and generally my lessons go for longer than one hour at no extra cost. I also get to compete on their horses at shows at no extra cost.
It takes me half an hour to get to their place, but its worth it. They're the only place in my area, that teaches both english and western. And $55 isn't that much, considering I stay there all day, ride on trails, get a personal 1 on 3 lesson because a lot of good riders ride there and help.
My instructors are the most polite and genuine people and its well worth the money.
My trainer travels all around my area, (she'll drive about an hour n/s/e/w) and I'm lucky enough to be 10 minutes from her house. We also board together, so I get to ride with her sometimes, and I also get the best lesson times. (6am lessons or late evening lessons)
I pay $40 for an hour lesson/training ride. She usually charges more, (I believe $35 for half hour private and $60 for an hour) but because my horse is literally in training with her and sees her 3x+ a week, we get a nice discount. I love paying less for more! =)
The trainers that my barn trailers out to are verrryy expensive, and are about an hour drive. One dressage trainer charged $100 an hour, and the event trainer charged $80 for a GROUP LESSON. (Alright, one was an Olympian and the other a Rolex rider... but still... talk about draining the bank...) We went several times to each in the winter, but saved our money for shows this summer.
