I work in a public library. We have a lot of seniors who come in who need help with setting up their home computers and with basic operations such as web searching, IM, and email. Many of them ask me if I can come to their homes (which I'm not really allowed to do). This might be a good home business for somebody who knows their way around a computer --- just place a small ad in the local newspaper and you could be in business. Volunteering at local retirement homes and communities could be another way to spread the word about your business.
