Depends on your skill set and experience, but I just found it and it looks promising. Fair warning: I haven't actually used it, so it could be not right for you, but worth a shot ... good luck.

I work in sales from my house. I sell fire equipment for a small company that is based in Idaho. The key to making it work is working with a family oriented company that is small. My "boss" knows that my first priority is my family. I try to schedule all my sales calls around their activities and limit their time with baby sitters. Since my customers (fire fighters, mostly volunteer) are also very family oriented, they are very understanding on my time balancing needs.

I have made between 20 and 30 thousand per year for the past six years and am usually gone from the house 10-20 hours per week. Most of that is at night when my wife is home and many of those hours are late night drives back from my rural customers.

So, if you can find a job in sales for products you believe in, it might work out for you.

When in doubt, call the fire department. Unless there is violence involved.

My uncle lost his job a few years back. He was close to retirement but did not want to sit around or play golf all day. He has an aviation background and he buys and sells parts for a few small regional airports and has made some decent extra cash. There are opportunities everywhere you only need to look for them or be creative about how you develop them.
