I got my instructor's certification through a college course a few years ago, and if I remember right, there's a minimum number of students needed to actually have the class, I think it's 7 or 8. It might be worth it to talk to your friends in the area and see if anyone else is looking to take the course, maybe your wife has some friends/coworkers that would be interested in a smaller class size. Like delta66 said the DNR might know someone in your area that can administer the course. Good luck.
