This is a brief overview of the whole publishing process - there are lots of choices to make, but I hope I've pointed out why most options should be avoided.
Here's a link to the Best publishing companies that aren't scams (though it probably isn't what you think).

Do what works best for you, but understand what you're gaining or giving up.
