I'm not sure if this has been asked already, but I would like to know what it takes to be a freelance editor. While I have no copywriting experience, I have a background in journalism - I have a MA and BS in the field, have been published, and run a couple of solo news blogs. So I am wondering if I have what it takes to branch out into freelance editing. I would like to edit and proofread novels, non-fiction and articles.
If its possible, where I can go? How do I advertise my services?
