Publishing your stuff is very easy.
1. FINISH THE BOOK. Finish it to the very last letter, faggot, and take your time editing it until you think you worked just enough and it's done. You heard me, bitch.
2. Go send it to all literary agents (in America; in other countries publishers often work directly with authors, though that's less convenient to both) you could find - send simultaneously to as many as you could.
3. Get published. Nothing can go wrong. You will get published.
NOTE, though:
Make sure your agent/publisher never EVER takes a penny from you. Remember this. Never, ever. If they say: sure, great book, now please pay editorial/reading/evaluation/whatever fees - even if it's a laughable few dozen bucks, tell them to immediately fuck off, and don't deal with them anymore even if they say your book is perfect - get away from them. Also, don't bother with publishers that advertise is a sense of "we need writers!" Real publishers don't advertise their "services" at all - as in, never, because they don't offer nos ervices, they're only doing business, and if publisher doesn't have good business, they wouldn't make any good of your book anyway, and thus you don't want them.
