I'm currently employed as an engineer at a large company. I'm having a bit of an early mid-life crisis. I don't enjoy my work. I'm on my second "career" in the company currently working as a six sigma / lean blackbelt in supply chain. formerly worked in engineering design. I worked for a smaller company just out of college & didn't enjoy that all that much either (though it was better than the large company).
I'll take the other tack.
WHY do you not like the current job?
Is it because of the people you work with?
The management?
Just the job?
Can you change jobs such that it would removed what you don't like?
Will changing jobs substitute on set of problems for another equally bad problems but for less income?
I don't expect and answer to the questions, just throwing them out for thought.
If you can get ahold of the Tuesday Wall Street Journal there was a column, Cubicle Culture, regarding changing jobs/careers that was interesting.
Regarding handymen. I have thought about it as a way to dump my current job in a large company.

When we where selling our old house we had a tough time finding people to just do odd jobs. We found people but it was kinda hard. If you present yourself as honest, literate and return phone calls I think one can find the work. Especially if you can get a name in area with expensive houses owned by people who can't do the work themselves but who have the money. Contact real esate agencies and pass around cards. Put your card up on the boards at grocery stores near the expensive houses. Maybe even direct mail those addresses.
Years ago I read one of the lawn care related websites. One marketing tool was the advertizing "books" that where bulk mailed. They where pretty cheap advertizing but they went to lots of houses. The percentage of people who contacted the advertiser was small but you only needed a handful of new customers a month. Hopefully that make sense.
Once you get known in a neighborhood you are like to get alot of repeat business.
Later,
