We are looking to build a full custom planner (inner pages content included) with the following specs: Size: A5 (148mm W x 210mm H) Inner pages: 90gsm or 110gsm paper Print: Grayscale / Black Cover: faux-leather (or something with a nice touch), 100% Lay-Flat Binding example: www.thecoolector.com/mind-journal-notepad/ Our original idea will be to make a planner for 3 months, however I want to see the price of a planner for 4 or 6 months.
