Have you considered the department of Ag in Colorado? Idk about there, but in Kentucky our dept of ag has a great shows and fairs department. They put on 6 preview shows, 5 or 6 district shows, 3 junior livestock expos, plus work the Kentucky Beef Expo, state fair, and NAILE. And that is just the beef cattle, they also do shows for goats, sheep, swine, and dairy cattle. The state's department of animal health might be another option. That's not exactly the same hands on job as working with a show string, no clipping, fitting, or halter breaking if that is what you like. However you get to work closely with the exhibitors and serve as a good role model. Also has good job security, retirement, and benefits compared to working on someones farm.
Not trying to talk you out of your current pursuits, just an idea.
