For instance, suppose that you, being a creative person, are able to make beautiful quilts. However, because of the time involved, you're only able to make two quilts per month. You discover that people are willing to pay $200 for each quilt you produce. The math says that you would have, therefore, an income of $400 per month. (Actually less, as there will be expenses related to quilt production, such as cloth and thread, to deduct from this amount.)

According to Pay Scale, the average salary for a freelance writer is about $24/hr.
