I guess I should have been a bit more thorough…
I do only have a few clients — however, there are many projects that I get on a daily and weekly basis with those clients.
Freelance billing rates come in many forms. I create content for my clients and the rates I have with them range from $150 — $250 per 1000 word pieces.
I am generally creating 2–4 pieces per week.
That generally gives me in the range of $400 — $800 a week.
I average it out to about $500 per week (of course it goes up and down depending on the projects and the workload) thus giving the $2,000/month I included in the article.
Sorry if I was vague!
Thanks for the feedback, I'll definitely be more specific in the future. I didn't mean to confuse you (or anyone)!
