grammar, spelling, punctuation, some reworking of sentences—a good choice if you’ve already spent a lot of time polishing story elements.
copy edits, reworked sentences as needed, story suggestions, and a master sheet keeping track of your specific story elements (characters, roles, places, phrases, objects, creatures, and events)—pick this one if you’re concerned about story cohesiveness or readers getting confused.
a nuts-and-bolts approach to writing and editing—this includes a consultation after the completion of your first draft (while you're still willing to make drastic changes if necessary), email correspondence throughout, and a far more detailed master sheet—an excellent pick for the author who wants an experienced partner throughout the writing and editing process.
an edit of the first 1-2 chapters of your draft. A good one to pick if you’re not sure which package is best for you—this edit will include both substantive and copy edits so you can get a feel for which edits best suit your story.
