Had to search but it seems that lulu allows 800 pages so your book can fit just right in

There are definitely some other publishers like No Starch Press who might help ya as well.

A standard color book with 800 pages will be around $25 at scale. So, if I sell it for ~$40, I would make ~$5.

Since I spend so much time, I decided to let people read it.
