NOTE: these rates are not set in stone and are only an average for this editor. The actual rate applicable to your document will depend on the depth of the edit, the quality of the writing, the topic matter, the proximity of the deadline, the length of the document and several other factors.
I have been a copy editor and writer at The Washington Post for the past seven years. I am a reliable editor and writer under strict deadlines (at The Post, there are three deadlines a night). I can be a reliable asset to anyone needing these services on a freelance or part-time basis.
