My rates are:
Copy editing – $50 per 1000 words or $50 per hour
Proofreading – $40 per 1000 words or $40 per hour
Structural or substantive editing – $60 per 1000 words or $60 per hour
There is no standard rate for freelance editors. In a 2011 national survey the Institute of Professional Editors Ltd (IPEd) reported that editors were charging an average of $62 per hour for their services. The survey reported that most freelancers (73%) charged between $40-$79. Source
I am flexible with these rates and will be happy to accommodate your requirements and arrive at a mutually beneficial arrangement.
