I run clinics here for about the same sort of riders. I bring a coach from the coast in here (we are semi remote, and about 5 hours travel from the hub of equine activities in this province). I can’t make recommendations for you because I am too far away from your area. But I can say that if your riders are not all super competitive, and cost is a concern, I would try to find a coach who simply wishes to extend their coaching business into your area, rather than a “known” and semi famous clinician. This is what I have done here. (I love Claudia C too, and have ridden with her several times over the last four decades). But the coach I bring in here is younger, not as well known, coaches at a show barn and rides professionally, rides EXTREMELY well, and has a great way with all riders at our clinics, he’s personable. Perhaps in 20 or 30 years, he may “make it” internationally, and be famous. And be able to command bigger dollars for clinics and lessons. But NOW, he charges us just what he charges his regular clients at his own barn… $50 per lesson. He takes a weekend off from his regular clients, and services his “remote” clients, drives an economical car to make the trip, and stays with us. He does not charge us a “day rate”, but I have to collect a minimum number of riders (10) to make the clinic “go”. Sometimes I can get 15 or 18 paying riders together for him (and I fit myself in to lessons where I can, for free). I add no charge for use of my facility, to keep costs down for local riders. So, working together, he gets more clients, in an area that he would not normally have access to, and I get coaching in a remote area, and the local horse community benefits with access to quality coaching which has never been offered in this area before. Many riders here are “stunned” with the difference in riding lessons, compared to anything they have experienced before, and the level of riding has improved dramatically. We now have a solid core of participants, who are now his part of his “regular” clients. It is as close as we can get here to having real coaching.
So I would recommend that you try something similar. If you can get a relationship with the right person, it stays affordable, and everyone benefits.
