Flash fiction is awesome for a couple of reasons: 1)short 2) can pay well. Those are good enough reasons for me. We talked about Duotrope earlier. It's a good place to find markets for flash fiction. For romance, I think Woman's World is awesome flash fiction market at $800 for 800 words.
Freelance work can be another good way to make money writing. You can use sites like elance to search for things that interest you from article writing to ghost writing.
Do you freelance? Have you ever sold flash fiction?
