Life of a Conservation Officer?

I have been a big outdoorsman for the majority of my life. I am at the point in my life were I need to decide what my future career will be. I am currently working as a Granite Fabricator/Installer and am trying to decide if I want to pursue becoming a General Contractor or a Conservation Officer. I would love to be a CO but am concerned about a few things. I meet the requirements for the recruit screening process and definitely know I have what it takes to make it through the training. My concerns are that my wife is currently getting ready to enter into Graduate school for Physical Therapy(duration of 3 years) and the problem is that if I become a CO, I run into the chance of us getting split into different locations. If I wait, then there is the chance of her having to relocate immediately upon entering her first job. If I become a CO before her schooling is over, then I may have to reside far away from our home. What would be some advice how to go about this if I decide that CO is for me. The reason I am at a deciding point is for the fact that my current job is causing physical damage from heavy awkward lifting and my age. I would like to start a career before I get much older. If you could also include general information about your daily job affecting family time I would greatly appreciate that as well. Thank you for your time and advice.
