The Whole Novelization Process...

Some publishers will accept electronic manuscripts these days -- most of them, really.  Don't worry too much about editing the whole thing, as 2 or 3 chapters (or 4 or 5 if they're really short) with a synopsis is all they're going to want.  Then, if they're interested, they'll get back to you.  DO NOT go with a publisher who expects you to pay them.  Unless they promote themselves as self-publishing or co-publishing houses, these are scammers. 

So, work on a really shit hot synopsis and a couple of good chapters.
