Grimr's Grimoire: a Book of Myths from the Spider's Web?

I'm contemplating writing a book called Grimr's Grimoire: a Book of Myths from the Spider's Web.  If I do, it will contain poetry, lore, myths, praxis, theory, and other things in it.  Writing it, I'm not concerned with.  I can do that easily, as I have time.  My big concern is the cost to get it published and if I could sell enough copies to offset that cost.  I figure I need to sell about 500 copies to break even.  Here's my tentative list of chapters:

1. Introduction
2. The Prophet and the Mirror
3. The Priest and the Bridge
4. The Poet and the Cauldron
5. The King and the Wasteland
6. The Wanderer and the Mask
7. The Mistress and the Blade
8. The Heidr and the Ten Thousand Things
9. The Vordr and the Compass
10. The Grimr and the Spider's Web
11. The Tvennr and the Eternal Dance
12. The Nagara and Everything
13. Ex nihilo
