Thinking About Freelancing

I've been thinking about getting back into freelance writing, and I have two possible markets to try. One is HowStuffWorks. I even have clips like they describe here. Now I have to come up with a killer introductory letter and writing resume.

A friend also told me about an educational publishing company and I'd love to become one of their freelancers. I'm hoping to get a referral for this one.

It would be exciting to get paid to write again!
