Materials that you want to use should be advised certainly. There is no special except for the text pages. The text pages paper can not be very thick like board books. Normally 200gsm lower or higher slightly is available. Because there are much folding, slitting, cutting and other paper engineering works involved, and finally the book should be closed before reaching to end users, the text pages applied can not be too thick, otherwise, there will cause some quality problem like bursting and out of glue etc.
If you want to get precise prices for actual book, we believe a sample book or detail illustration for each page is necessary. That is because we try to get more ideas about how each page works, based on this information, we can estimate labor costs to make them by hand. The slower the working, the more complex the function. Slower working will cause much more time and costs to make the pages. Of course, you could adjust your design based on actual producing needed, we hope to create interactive and efficient communication between us, to help you get ideal pop-up books in high quality and reasonable prices.
