What you have listed is pretty much my day job - I teach 'survival' skills to military, SAR, emergency services, production companies, individuals; i run foraging workshops and courses, write about foraging for a few places, and also have a book out next month; I run 'bushcraft' courses but hate the name really. It's become a weird quasi-pasttime involving sitting by a fire carving a spoon - i prefer 'wilderness skills' as it covers more of what folk can actually go and learn to do, not just copying what Ray did on telly 20yrs ago...
