I looked into guiding when I was your age. There actually was a guide school that I considered in either Montana or Colorado (can't remember at the moment). Fortunately I had the sense to go to college instead, and never did venture into guiding. I think it may have been a fun experience for the short term, but certainly not something I would have liked for the long haul. Working for an outfitter, you can expect poverty wages, exhausting treks, and limited (if any) personal hunting time. If you survive that and learn the business, you may be able to go out on your own and do a little better. Definitely have long term and backup plans.
