SO many great responses, thank you all. Now to try to answer all questions...
1) My experience includes: cleaning/maintenance, removing/traighening "stuck" slides(or bent) and mouthpieces, fixing broken valve guides. Relatively minor work, but useful in my experience.
2) I'm really looking to get to the point where I would be able to repair my own horns and/or the horns of my students. I do recognize that it would take a few years to get to that level of proficiency. So I'm not really looking to make a profit from it, but would rather have the experience to satisfy my curiosity and for convenience sake. However, I was thinking about building up a shop business in my later years.
3) A trade school sounds optimal, but the ones discussed seem far away (at least from where I am currently, who knows where grad school will take me?)
4) I was going to look into great Southern Winds here in Gainesville, Cody, but I was considering looking into Hoggetowne as well. I know there is one other repair shop/store in the area.
