If you have a knack for fixing things around the house or in the garage might make some extra money being a general handyman. People are always needing small things fixed around their home so it is a great side business. Customers like the idea because they can hire one person and they are usually cheaper than hiring a huge construction company.
Finding customers isn't as hard as you may think. Craigslist always has ads for people looking for a handyman. Also, if you can network properly with your family and friends they will often refer you to their friends. Once you get a good referral business going you will get a steady flow of business coming from all over the place.
