Is there a thread which breaksdown the cost for Lulu and create space. I just think create space takes a lot more money than Lulu and vervante. Am I right?
First, I have never heard of Vervante and only just skimmed their site. I haven't been on Lulu in years. So everything is based on that.
Second. I don't think people will be able to answer your questions about Vervante. The pages I saw on their site all said "contact us for a quote" So, unless someone has happened to have ordered from them in the recent past, no one is going to know how much they charge. If you have gotten a quote from them, then you should post what they're asking for what services so that others might be able to fill in the Lulu, CreateSpace side.
Third. It is hard to say anything about pricing because you do not clarify what you're looking for. If I ask "is Ford or Chevy the cheaper vehicle?" No one can answer because that is too broad.
So: Are you looking for hardcover, softcover, B&W interior, color interior.... ebook formated for ePub, Kindle, PDF... do you want Print on Demand or 500 copies shipped to you to store in your house... where and how do you want to retail this book?
I do suggest that if you are publishing a book at the $39.95 price mark (and it is not an authoritative source of information) that you try to avoid all up front charges so that *IF* you do not sell many copies, you won't be out a lot of money.
Good luck with your book.
