I wrote and published a book www.infinipede.com in 2003. I self-published. In the children's book world that is a hard path unless your book has a really great niche market. The children's book industry is very unfriendly to self-published authors. Plus you have to be super-motivated for marketing. One woman who has done super well is Laura Duksta, who wrote I Love You More. Look her up. There's lots of books at the bookstores like Barnes and Noble and Borders in a section on publishing. All kinds of how-to materials. Also there's a self-publishing guide if you go that route. I forget the author but its from Parapublishing. Look in your area for writer's clubs and such. If your target audience is children look up SCBWI. Good luck.
