Thanks for all the replies guys.
First of all it's nice to know that it is possible, as a few of you have said.
Luke SkyToddler - you're completely right when you say 19 is young to be making decisions like this and your words of caution are very helpful. I'm not absolutely set down this path and it is useful to know the opinions of people with a much greater wealth of knowledge than me. The bush flying was to an extent just an example (although it does appeal) and thanks Council Van for the suggestions closer to home.
Your solution is well worth bearing in mind Genghis. I'm afraid I'm fairly set against military flying. Exciting though I'm sure it would be, I don't think the lifestyle is for me. Your combination of qualifications sounds a good way of doing things.
Thanks again for the replies. I look forward to more thoughts - notes of caution are just as welcome as encouragement.
