Hmmm. An interesting one, this.
Enthusiasm is great and will certainly help the delivery along quite well. People seem to confuse the need for the 'experience of teaching' with 'experience'. I cannot vouch for your bushcraft experience but I would assume it's pretty sound but I would imagine that your teaching experience is nil and therein lies the problem. As others have suggested, make the investment and go on a couple of courses, watching and listening to the instructors very carefully. Try and note down the things that contribute to a successful lesson/session, including timings, pacing, resources, shifts from talk to demo to participation. Then, it's a matter of practice, practice, practice, ideally with a 'user-friendly' small group.
Do be aware that there are huge differences between what kids can do, what teenagers can do and what adults can do, not just in terms of out-and-out strength, but attention span, loo breaks, drink 'n' snack breaks and, bizarrely, levels of discomfort that your clients are prepared to endure. Be prepared to be very flexible with the content, pacing and goals of your sessions: if you can only operate within a rigid scheme, you will become frustrated and your delivery will be poor and, actually, the whole thing of teaching is probably not your bag.
It is desperately important that you become a reflective practitioner. Always be honest is the way you appraise your performance and delivery of a lesson and take the time to make notes of how you can improve and what you can improve for the next session. It makes very informative reading, looking back at the assessments to the lesson plans that you absolutely must generate.
Liability insurance, a really, really good wilderness first aid course (with the necessary investment in the kit to cope with life's little travails), food and hygiene qualifications (if you're intending to feed them...) and an absolutely rock solid understanding of what is considered 'best practise' (a.k.a. 'safest techniques' - not necessarily the most flash but mandatory for success) for each of your teaching modules is a starting point to which you add your enthusiasm and that elusive ingredient, experience of teaching.
Before you start off, do research your market: do you actually have a client base to start this enterprise? Is there scope for it to expand? If folk aren't interested in what you have to offer or if they don't trust your lack of experience, then you'll have to go away and plug those gaps.
I don't wish to pontificate or be damning or parental about it but these few observations come from being a professionally qualified teacher AND an alumnus from John Rhyder's year-long Bushcraft instructor's course. If I can be of any further help, please feel free to pm me.
Good luck.
