For a typical ~70,000 page book without images, it's something like this, give or take 50% on each metric:
$1,500 editing
$300 proofreading
$200 Cover
$200 layout
$100 Proofs
$200 Software
For a typical textbook 30,000 words with lots of images and diagrams
$700 editing
$1000 consulting
$2000 image licensing
$200 proofreading
$1000 layout and cover design
$200 proofs
Note: These would be for Self Published titles destined for KDP / Ingramspark
I'd say hiring beta readers too early in the process is something I regret spending money on.
