I offer a sample edit for the first 1,000 words. I charge $350 for novels around 50,000 words. If your word count is much lower or much higher, email me at firstname.lastname@example.org and we can discuss pricing. I have edited for publishing companies as well as independent authors. I have just finished a novel for a publishing company that also develops indie games, and this project is part of a major release soon to come.
The price is for copyediting, but I will point out inconsistencies and anything else I find wrong with plot or character development. I will also suggest ways to reword paragraphs that don’t sound just right. I will run through your story three times to make sure I catch all the mistakes, and leave plenty of comments on my experience as I read.
If you’re interested, email me and we can discuss things further.
