I've received your email :D and sent you a download link for the four templates I found that looks somewhat useable. I use a 15 year old InDesign program though, and don't know if they are on the updated InDesign program, but I think it should work fine.
I hope you have fun with your project and manage to complete the NDS book. I think people would be very interested in a book/guide for that system :D
