A pal of mine returned from travelling and started a small business: "no job too small just call Paul". Basically he's a handyman doing small jobs that other tradesman dont want to do and that people for lots of reasons dont want to or cant do themselves. He only describes himself as moderately handy and wont take on anything too technical. He has a small van, the basic tools and charges about £10 an hour. Most work come word of mouth although he very ocassionaly advertises in the local paper and he has some sign work on his van. He seems to do OK and could drop it all at any minute to go off travelling again (but I think he has got it out his system now).

Back to the OP though, handyman work doesnt fund travel while travelling, but may be a way of getting some capital to start. To fund travel while travelling one needs to have a skill in demand worldwide. Teaching english seems common based on what others report, but I always thought something that humans always need on a regular basis is best. SO: haircutting, cooking food, medical/nurse/first aid skills, tailoring/seamstress skills, the ability to fix the unfixable (electronics has got to be a good one here), and other stuff like that have always seemed to me to be things where work is always in demand everywhere, or that could be easily and quickly established almost anywhere. Local competition will be an inhibitor of course.

Just my thoughts. I have none of those skills, sit behind a desk all day (in an interesting job though) and like to have more than enough money to travel with. Living on a shoestring is not my or my wife's style.

Good luck with it all Ted.
