Well, I’ve been looking at publishers and literary agents sites, and basically I think it’s safe to say that they don’t want to know you until you’ve already done all the work you will be paying them for!
Self publishing sites are a lot more friendly, though some of them want to part you from a significant chunk of money before they publish anything. Others are surprisingly generous, some only taking a small cut from your sales. They tend to be the epublishing companies. I suspect that will also be because they have to do bugger all work to publish you.
I have to say that the more I read the less certain I become. About the only thing I’m sure of is that any author will have to do all their own promotional work.
