Copy editing includes reading for spelling, typos, punctuation, missing words, double words, etc. This editing process includes checking for inconsistencies, continuity issues, and/or accuracy.
Done at a later stage than initial copy or line editing, proofreading is more detail-oriented. In this stage, I will not only check for errors that may have been overlooked or introduced during revision, but also for issues like missing italics, incorrect page numbering, missing quotation marks, typos, spacing issues, etc.
9-13 ms. pages/hour at $25 /hr
Line Editing/Substantive Editing
Line editing has more to do with the writing itself. In this capacity, I will read for content and writing style, run-on sentences, bland language, stilted dialogue, info dumping, head hopping, confusing scenes, etc.
$0.012/word for the first round of substantive editing plus 50% of the total for the second round, further rounds will vary as necessary
