Chris, before you go ahead may I suggest a broader publicity push? I cannot believe that with a membership of well over 2500 people only a mere ten are interested - I suspect most either never knew about last year's calendar or have simply forgotten.
You are ideally placed as Webmaster to highlight the availability of calendars across ALL forum sections and threads, so how about placing a banner notice on the home page and some sort of corner flash or pop-up alert on every thread so that everyone, even casual browsers of the site, get a prominent reminder that calendars are available? They should also be listed in the merchandise section, for loved ones of 126 fans looking for Christmas gifts, and further afield, how about an eBay listing?
Certainly you can count me in for a firm order, and if you generate significant business and hence the physical work required to get them packaged, sent out etc, I'll be happy to help out. Is it possible to set up some easy-pay mechanism using Paypal etc so that impulse buyers can be captured?
Perhaps members in other countries or with strong links there can act as local distributors.
