Understand that guiding encompasses a wide variety of things. The main skill you need is PEOPLE Skills. Even before being able to find animals, or handle horses and mules, or skin critters. Your biggest clients may likely be people you dislike.
You might lead trail rides in the summers, guide fishermen in the early fall, campjack or cook in the Fall, dog sled or snowmobile in the winter, and starve in the spring....seldom will an outfitter have year round work for you. You will likely have 2 or three jobs a year and no retirement except what you save. If you are guiding in the west, you should be able to shoe a horse, sharpen and run a chainsaw, run a single or double handsaw, repair small engines, dig a latrine, sew up a tent, do leather repair, pack a horse or mule, tie on a fly, match the hatch, mix a drink, all before lunch then fix a 5 course meal with 3 ingredients and smile the whole time. (mild exaggeration to prove a point)
Do it while you are young and footloose with minimal debt. it will be a great experience that will enrich your life. Just don't expect to go right to pointing out big bulls to nice, polite and appreciative clients. Even when you start out as a camp jack, your position has value though. Don't work for free. You might only get $500-700 a month plus meals and a bed, but it is where you start.
