I've taken many photos of THE BOYZ, so I decided to make a photo calendar online at lulu.com.
This calendar, called Cockapoo Dogs, is for sale as a Christmas present. Here's the calendar: http://www.lulu.com/product/calendar/cockapoos/18619731
You can also make a custom photo calendar on lulu.com as a Christmas gift and then buy it for a reasonable price. Once it's completed (published) lulu will send it to you. It can have custom dates as well as special photos.

Remember you can use the same steps in the squidoo lens to build an online calendar to sell!
