Yep i did the course two years ago at woodcraft school, very worthwhile despite the cost!! I would thoroughly recommend it to anyone who wants to go into teaching bushcraft or just wants to improve their skill base. However it is just the beginning, and you will need to increase your skills and maintain your specific qualifications to carry on business after the first year, e.g. first aid, food hygiene etc. Its hard work and it is most definitely get what you put in!! Once you start, begin putting together a CPD for future development.
Enjoy
