Note that I charge approximately USD: $0.015 (1½c) per word for line editing, dependent on the quality of your manuscript. I include copy editing and proofreading when I do line editing because I hate leaving even the smallest thing undone. However, just before you publish, you ought still to get an independent proofread done by someone who isn't familiar with your manuscript.  A good line editor will identify and correct: so on You can also use a line edit to prepare for your content edit, which should result in a quicker turnaround time and a lower rate from your content editor.  Copy editing does not replace the work of a content editor who will look at your manuscript at a macro level and advises on things like restructuring, rewriting or deleting. A content editor may also be called a developmental, structural or substantive editor and would typically review your manuscript when you've finished self-editing.
