I am wondering how much it will cost if we want to publish the black-and-white-version. Could you please give us a quotation? Because the cost of the color-interior is a little expensive, I wonder if black and white books are cheaper. But we hope that the part of the card is still color, only the part of the inner pages are black and white. Also, it seems that there are similar books published in the United States, such as Doreen Virtue's card book, the name is Archangel Oracle Cards. We hope that we can do the same as her.
