Deborah,
I think this is great information. I would add one thing to this list: consider what else you have to offer beyond what you already do. I think a lot of us are having to reassess our skills these days. For example, I realized that as the market tightened for real estate writing that I could shift into personal finance writing since the two fields are closely related. Now I market to clients who need either one of these subjects addressed. P.S. Thanks for the mention!
