book-publishing!?

what should i do if i wanted to publish a fantasy book? is there anywhere i could go in the LA area when i’ve finished typing it on Microsoft Word?

maybe you can go to a book store and look through all the publishings’, and write down the ones you like; then go on to their websites to get a phone number to call; better yet just go on to random publishing/ publishers’ website/web page
GOOD LUCK!
