Self publishing is really hard work and I'm not even talking of recouping my investment yet. I prefer Authorhouse to Lulu because they're more experienced and with wider reach. So they're responsible for making the book available to online retailers, mine is to promote and keep it out there. I'm trying my best but it's easier that I don't have a full time job.
Authorhouse publishes children's books too and you are the one who pays for it. That is why they're not bothered to read it before accepting to go ahead. They do not pay you, you make money when you sell the books. When you are ready, you send them the electronic copy, that is what they work with. And it has to be the complete manuscript.
I hope that helps and all the best in your writing efforts. Let mem know if you have any more questions.
Best Regards,
