I just went through the whole self publishing thing. It is a daunting task, but completely doable. Most of Amazons books (I'm told) are printed by IngramSpark.com. You can sign up there, and try the various layouts (book sizes, weights of paper) to see how much a 'book' would cost. Then you can see how much you would have to charge to make dime one. Once you are satisfied with the look of your book, then you have to market it, another daunting task. It does take you away from the creation aspect (the best part) but it has to be done. Good luck!
