My wife has built a business providing the exact services you cite, and she does it without the author "selling the baby," or doing obeisance to doctrinaire, facile, liberal publishers.

The authors of these books could certainly use her services, me thinks.

There are actually many, many good books out there that will never see the light of day if the author doesn’t do it (relatively) themselves.
