I've actually been working from home for a couple of years now, but I was working for other organizations. In the last few months, my friend Tamara and I started our own company. We've been calling it the Berry-Brewer Agency, but we're debating whether to add the word "freelance" or the word "writing" in there to be a little more clear about what we do.
Currently we do a lot of writing for the web: seo articles and such; but we're attempting to move more toward supporting other small businesses that need good writing and editing.
As part of the Berry-Brewer enterprise, I help maintain the Freelance Parent
blog on the eMoms at Home network. I've also been writing Something Good
for the last year, although it's not getting the attention it deserves lately.
