Companion book printing questions

So I'm pushing forward with my tarot project and am looking into getting a companion book printed as well. I figure that I'll be selling a lot fewer of these books, so am hoping that people here will have suggestions on where a good print on demand shop for something like this might be.

Also, do you think it would be advisable have the full text online somewhere as well? I'm not really looking to make a profit on the book, and if I can just have them printed as needed at-cost, then I really have nothing to lose by giving a digital copy away for free online.

Quite a lot of people ONLY supply a pdf these days.

Other than that, the easiest is probably amazon's createspace thingy. I've never used it, but many here have.
