Absolutely NOT!! Do not give them money. I know it's past the 10 days, since you posted this 2 weeks ago but I hope you did not give them money. I have sent manuscripts out to many publishing houses and have learned the in's and out's of how it works. That is never how it works!
Please tell me the name of the place. Did you find them from a publishing house directory? From an agent? They have books with publishing houses listed and each one wants something different. So you know who to send to and who not to. It's a great source to have before sending a query letter with a few chapters or a cover letter with your full manuscript if it's short like a children's picture book.
I would be extremely interested to know who would scam people like that. I want to see if their name is listed, as well. I doubt it but you never know if they squeaked in. Are you sure it wasn't an agency? I have seen both agencies and publishing houses that are scams but they usually mail you or you see an ad, which is not the norm ever!
Please let me know the name of the place. I would greatly appreciate it and if you tell me the type of book it is, I can give you some online sources to help that are not scams at all. They are not publishing houses but they are the real deal as far as who people use. Plus I can tell you which book that is a must have from the bookstore but I need to know if it's for children or adults.
If you did send to them, let us know what happened after you send the money. But give me the name. I'm dying to know. I will give you feedback on them.
Thanks for asking about this and I hope you did not send it, from what I saw the first person said but I didn't read through the posts since I just hit "answer this question." I'm going to read through now and I'm sure that's what they told you and maybe you even responded with the name already. Sorry I didn't read through the comments first but I couldn't believe it and had to respond right away, although too late.
