Inexpensive bulk calendar maker?

I've been taking nature and animal photos for my Agri-science cl, and my teacher said i should make stuff like postcards, calendars, stamps, etc. to sell at our town's fair this fall. However, every bulk calendar maker i find is extremely expensive. Does anyone know any great websites that offer bulk calendar creators that are inexpensive to order? If anyone knows any other websites that i can make products from photos for cheap, I'd really appreciate that as well. Thankyou :)
