Are you the one everyone calls when their computer goes south? Why not get paid for it by fixing the computers and answering the technical questions of helpless strangers? A good Web page touting your services is critical here. Use keywords and make sure you're specific about the local boundaries of any on-site service. Most people looking for help will Google "city name tech support" or something along those lines, so use your best SEO-fu to design a page that beginners will understand and search engines will love--remember, these are frustrated people who can't figure out why the fonts are so small on their new monitor, so simple and clear language is key. Craigslist is a popular spot for advertising your wares when business is slow, but be sure to elevate your postings above the riff-raff.
10. 'Personal' Phone Service Operator
When all else fails, you can always talk to people on the phone. This doesn't take a lot of skill or much in the way of setup beyond getting a 900 number or 800 number (plus a mechanism to accept credit card payments). Want to give out recipe advice, sports-betting picks, or psychic readings? Whatever floats your boat, chances are good that someone out there is willing to pay to listen to you say it. Of course, a lot of these services tend toward more "mature" offerings, but we here at PCWorld would never, ever judge you for that.
