This is being asked a lot lately. Some ideas:
What are your interests, aptitudes, skills or talents? There might be a particular service you can offer. A friend of mine with strong English skills corrected/edited essays for high school and college kids, and eventually started her own editing business. Another acquaintance tutored kids struggling with math. How about custom knitting, sewing, mending, altering, cooking ready-to-pickup dinners, decorating cakes?
