Share 'How much cost is involved with CreateSpace?'

Hi,     I realize I am new here, I need serious help. I published A Dream in the Night in ebook through smashwords. I want to finish the dream and have it in print. I have a word version ready.       I checked out lulu, and after reading a few posts in the forums, decided against it. I heard about Createspace through here. Any advice is greatly appreciated. Thank you very much! :)
