I just published my fourth ebook novel recently and I've used Ebook Launch every time with very satisfactory results. They always promptly turn around the cover and manuscript formatting - and as an added bonus, they always promptly and happily answer even the stupidest questions I come up with. Adrian is very easy to work with and Dane has repeatedly come up with cover ideas when I was fairly sure that it couldn't be done.
Rates – Most online book editors are freelance editors, which means they set their own rates. Editors may charge per word, hour, or project. Editing is a valuable investment in your book as a good editor can turn your story from meh to amazing! But the highest rates don’t necessarily mean the best editor, and the lowest rates could be wasted money. Definitely take rates into consideration, but don’t select an editor solely on price.
Proofreading is the vital last step of the book editing process. After your manuscript has received its professional edit, your book proofreader will perform a final review to fix any remaining mechanical and grammar issues before your book is printed and published. Proofreading is not a structural edit and instead focuses on eliminating minor mistakes and inconsistencies.

2. Copyeditors aren’t the last line of defense when it comes to a book’s mistakes. Formatting, which is done after an editor has done their job, can lead to unintended errors being introduced into the text. That’s why it’s important to hire proofreaders to comb through edited text *after* the book has been formatted for print or digital. Proofreaders are your last line of defense—but they’re human too.
