Probably not quite the same but have you looked into doing a survival/bushcraft course?
Ray Mears does some good looking ones (on my list of things to do in the future)
Ray Mears Bushcraft & Woodlore Camping Equipment and Courses
Even if you eventually decide to go out totally on your own.. I would recommend doing something like this first so you know what your getting into & how to survive.. (cause the alternative aint so pretty)
