RE: Guiding as a career
If you love being outside, and you love hard work, then you will love being an outfitter.
If you like to hunt (meaning acctually take game) then you will hate it. Every minute of your season will be spent with paying customers (if you are good that is), with little or no time left for yourself.
I guided fishing trips with a full time outfitter one summer when I was in college. It wasn't too bad, but I decided pretty fast that its no way to make a living. People expect WAY WAY too much out of outfitters for the most part, at least when it comes to success rates. I cannot make a fish jump in the boat, but I can put you on fish, with good equipment, safely get you there and back, and provide good company and a good lunch in the process. Thats how I looked at things anyway, and I made about $200 a day just guiding for flatheadcatfish out of a rubber raft in the rapids.
My advice, go ahead and get an office job. Or heck, it doesn't have to be an office job, but get a job that will allow you to make enough money, and have the flexibility of schedule to let you hunt whenever you desire when the season is open.
I am going to open up my own archery shop, mostly a range, but a shop too. I want to be my own boss, and there is a real niche in the market where I live for a good 3D course. Since in my county, it is illegall to discharge a bow in an area zoned as residential, there are plenty of folks who want/need a place to shoot safely and legally. That lets me be around what I love, while letting me make my own schedule, and work for myself.
All in all, you have to follow happiness. If you do that, then you'll always be happy.
