Are you sure?
All right, then. Let's look at your options. You can
A) Find an agent and shoot for the big dogs
B) Find a small press
Let's evaluate your goals. Do you want to reach a lot of people, a certain group, a few in every city, or the whole world? Do you want to be involved in the decision-making, or just get told the decision? Or do you want to make the decisions?
Because, peoples, the amount of control you have over your finished product depends a lot on what avenue you take to get there.
Self-publishing will allow you the most control. You choose your book cover. Your plot is exactly what you make it. Your characters grow (or don't) depending on your discretion. You have no editor.
That's not necessarily good. But it can have its advantages.
But let's face it. Having an editor generally (99.9% of the time) improves your manuscript. Everyone needs one. If you self-publish, that usually means paying someone. If you choose options A or B...you get an editor for free! Doesn't get much better than that!
There is a price, though. You want to get published, and you're not Stephen King. (If you are, please say so in the comments so I'll feel really cool.) Your editor/agent/publisher doesn't like your title. There it goes. Your e/a/p doesn't like your MC's boyfriend. Bye-bye, bug, bye-bye! Your e/a/p wants to change the word 'Jesus' to 'God' in your MS. Or whatever. Just imagine.
THEY ARE THE POWERS THAT BE.
Still interested? Still want to get published?
Good for you. Then do it. But do not think for one moment that just because they want your ms means it's going to stay in one piece.
