A copyedit includes:

Assessment of sentence structure

Evaluation of manuscript for grammatical errors

Stylistic formatting for your choice of APA or Chicago Manual of Style (if no preference is given, I automatically refer to the Chicago Manual of Style)

All rates are already reduced and based off of the average rates as set by the Editorial Freelancers Association. Their rates can be found here: https://www.the-efa.org/rates/

As it is set hourly, the average pages edited in an hour for copyediting are 7-10 pages per hour. This is dependent on a number of factors, so that is not a set ratio, please keep that in mind.
