I don't want to discourage your dreams, but would like to suggest that you broaden your perspective. Based on the posts I've read on this board, DMs and Instructors aren't paid very well, jobs are hard to find, and there are a lot them who seem to be regularly frustrated by their customers.
My perspective was changed a few years ago by my friend that is an electrician, and hates it. But he does excellent work restoring old cars as a hobby, and loves that. I suggested once that he look into auto restoration as a career, and he told me that he was afraid he would end up hating it if he did it for someone else.
When I first got certified I thought briefly about going the commercial diver route, but decided that if I was diving professionally in lousy conditions, I might not feel like diving for pleasure. I see posts from commercial divers who still dive for pleasure, but I don't think it would suit me.
Where I currently work, there's a dive team. I thought briefly about trying to get on it, but the dives they do aren't glamorous, and, again, I don't want to ruin my hobby.
Just a thought, but if you love diving just for the experience, and don't have an overwhelming urge to instruct others in the sport, why not pursue a career that requires travel to costal locations, then dive for pleasure in conjunction with the trips? That's what I'm trying to do. I currently have a temp-to-hire position with a company that makes equipment that must be installed in the ocean.
If this dosen't interest you, another option might be to pursue any career that is in demand, and look for a job in an exotic locale. I know that a previous poster mentioned teaching, and I know that there are others out there.
Working as a tour guide or otherwise in the travel business might be another such option. As a travel agent or tour guide maybe you could organizing dive trips, being reponsible for the people while on the land, but dive without the burden.
Just my thoughts on the subject...
