Sometimes the editing process never ends.
At least, it feels that way.
When you're hiring an editor, you want to make sure you fit with expectations and timelines. Basically, let them know what you're looking for, what you want done, what they charge, how long it takes, how many people are already in line, and when you'll be hearing back.
Remember editing is not super duper fast. Not if it's being done in depth and well.
So what I'm saying is... I'm a writer, which means I edit, or work on edit notes I get from Critique Partners, Beta Readers, Editors, Publishing associates, and anything I get-- All. The. Time.
I am NOT an Editor.
But, I freaking edit.
