If you believe the book is good enough, look for a literary agent. It is very difficult to get published by an actual publisher by simply sending in your manuscript. They get 100s of these in a year. Therefore, if you want to go that route, get a literary agent.
If you wish to self-publish, don't just take it down to your local printer. They may do a lousy job, messing up your title page, etc. There are various companies that do this. I've seen good products from Xulon Press, but their website is currently not responding. Anyway, look at the product before you go with any of them. Also, they may or may not do editing work for you. All authors without exception need an editor, no matter how good a writer they are. If you have a friend or relative who teaches English or creative writing or something like that, they would be your best bet.
Be aware that if you go the self publishing route, you may get a lot of profit, but probably not. Also, there are self-publishing companies that do your advertising for you, but some do not.
Then there is something called "print on demand." I don't know much about this, but my brother self-published a book and printed them up one at a time on a book printing machine somewhere (I don't remember where) when he got orders.
So, what is your book about?
