There are a lot of editors out there with no actual editing experience working with a publishing company, newspaper, journal, or other business that requires a high level of expertise and provides training for editors. Without working in such a position, it’s very difficult to obtain and master the skills required to become a great book editor. It’s not impossible, but it is unlikely.
I recently contacted Ebook Launch on the advice of a fellow author, and I am extremely pleased with the results. Dane was professional and very prompt, always keeping in touch with me as the process unfolded. I had both my ebook and print versions of the cover within a week of paying for them. They were professionally done, rivaling anything I have seen from the top publishing houses. Excellent work!
That said, I don’t recommend going to publication, particularly if your book is intended as a revenue-generating venture or as a vehicle of professional promotion, without making sure that someone with an eye for detail has gone through the entire manuscript and ruthlessly noted every typo, every spelling error, every misplaced comma, and every ambiguous sentence.
I would add the suggestion to be prepared for the editor to request a look at the manuscript (not just a short sample) to prepare an accurate estimate. This has been my practice for some time, and it allows me to provide a flat fee for the entire project. This makes budgeting much less complicated for the author, although of course I am willing to bill by the hour if preferred.
Working with a professional is always the best choice, so if possible, then save up to work with an editor. But of course, some writers can't afford this, in which case there are some other options. You can barter with other writers in the same genre, editing each other's work, or providing other services you might be more skilled at e.g. Marketing tasks.
In fact, Pressfield writes, “Resistance is experienced as fear; the degree of fear equates to the strength of Resistance. Therefore the more fear we feel about a specific enterprise, the more certain we can be that that enterprise is important to us and to the growth of our soul. That’s why we feel so much Resistance. If it meant nothing to us, there’d be no Resistance.”
