First of all, you should look for a literary agent before a publisher. I would recommend reading How To Be You Own Literary Agent by Richard Curtis. Either you will be able to act as your own agent or you will realize how much you need an agent. An agent will help you work with publishers.
Secondly, no publisher will publish a book without having their editors look at it. No matter how good of an editor you are, you need a professional to edit it anyway.
Good luck publishing your book.
