Self-Publishing a China Photo Book?

Since coming back to America, I've been flirting with the idea of self-publishing a book of my best photos from China. I'm thinking a soft cover book with, mostly, 5 x 7 inch and smaller photos (ie. not a huge, hard-back coffee table book).

I'm wondering if anybody reading my blog has ever done such a thing. I haven't talked with anyone who's self-published a book. Any advice would be most appreciated.

Also, would any of you, Mark's China Blog readers, be interested in buying a book of my best photos? I imagine that I'd be able to push several copies of the book onto family and friends, but would also like to make it open to a wider audience (if anybody would actually be interested in buying it).

I literally have thousands of photos. Some of them can be found here. Several really good ones are also on the post I made on Sunday. I have many, many more photos that either aren't on this blog or aren't on the internet at all.
