Inquiry about self-publishing

[ahedonia]

I had an idle thought the other night, while out walking the foster-dog-who's-getting-closer-and-closer-to-not-being-foster-at-least-in-my-mind-anyway.

If you want to self-publish a book, what does that cost and what do you get from it? What's a good service to turn to if one wants to do that? I might want to put together a bit of navel-gazing.

Thankee.
