Since you are in this forum, I'm guessing that you might be good with computers.
You could make-up flyers to pass-out around your neighborhood, shopping centers and churches offering to help people with their home computers.
Offer your services based on what you know already like installing a new computer, connecting it to a printer, setting up a home network, loading applications, setting up email accounts and internet applicationsÐfor the latter two jobs, you can get telephone help when needed from your customer's ISP).
Keep your prices cheap, show-up when you say you will, be honest and don't expect any payment if you can't do what you are asked.
