Earlier quoted context omitted.
The first publisher costs to get cut in this scenario are the copyeditor and proofreader. This is a rudimentary but still fair description of the basic process of trade book publishing, and you conceivably could make more money self-publishing, assuming sales are roughly equal in both cases. They probably won’t be, but you could still come out ahead. A few folks have done quite well with it, but you will be doing all…
(Disclaimer: I am the author of the linked article.) NEVER cut your copyeditor and proofreader. NEVER NEVER NEVER. You still have the responsibility of creating a quality product. You can sell a few buckets of poo, but that market is very small. Sustained quality is a prerequisite to a writing career.
I was looking at https://www.ingramspark.com/environmental-responsibility and saw this:
> The purpose of print-on-demand book manufacturing, is to reduce our environmental impact.
That misplaced comma is already enough to make me think these folks aren't serious about books (money from books, sure, but not books.)
