If you want to self publish a decent quality photo book, options like Blurb are OK.
If you're going after the higher end market and color accuracy and quality are paramount, you'll want to look into options like Asuka, Edition One, etc.
If you want information on how to write a book proposal and market it to publishers in the hope that they'll pick up your book, then I recommend the book link that I posted above. It covers everything from making a Blurb book, to getting picked up by an actual publisher.
Lots of great ideas, resources, and marketing strategies, too!
