Here is an interesting conversation from Reddit regarding, "an affordable self publishing resource:" https://www.reddit.com/r/selfpublish/comments/7x3mx2/looking_for_affordable_book_printing_company/

#mathselfpublishing - of course this is from about 5 years ago, but a full answer. "Ingram Spark" @IngramSpark is recommended, but it sounds like they have strict input file requirements!

Looks like you can do both print and an Ebook for $49 per title as a base price on Ingram Spark.

#mathselfpublishing looks like they have a nice tool online to help you calculate how much a print edition would be. Let's say I'm looking at doing a 5x8 coffee table companion book, standard color, matte, 100 units.
