I'm sure many of you play the role of computer expert for your family and friends. Computers are difficult and where do people go if they want to network machines in their house, upgrade parts, recover from crashes, etc? I'm wondering if I can turn this need into a small side business.

I live in a fairly rural area (but with lots of McMansions) where local businesses and personal service are more the norm then big box stores. I'd only be looking for a couple of jobs a week so I hope I could get that kind of business from local advertising. My advertising pitch would be that I will come to your home on your schedule (evenings or weekends) and help you do the things you don't know how to do with your computer.

Anyone else tried something like this? Any advice, particularly on what rate to charge?
