It may not pay well, but there is a growing demand for this. Write 200-300 word articles and submit them to article directories. Potential clients include bloggers, marketers, and small businesses. You can write articles in a niche in batches and sell them as a package to one or more clients, or you can offer your services for hire per word or article and let your client give you direction. A foundation of keyword research is important to succeed at this job (unless you're just taking direction from a client), but keyword research is learnable.
