Personally, I like Ella's idea....what you can do is to show a couple of sample pages on a website, and if the people like it they can enter in their credit card information to download it. If they don't have a credit card (such as myself), they can send in a check or money order for an authorisation code to download it or receive a disk with the calendar on it.
