I tried to figure out a way to do what you are proposing and ultimately I decided to go online commercial with UPrinting.com
They are not cheap IMHO but worth the cost, the quality of the printing was spectacular: color, finish, packaging, with envelopes.
I found it helpful to talk to a rep online and they walked me through the process of dropping my images into their template. They do an automatic CMYK conversion when you set up your image.
You do need to do many multiples of a single image going this route, each image printed incurs a separate shipping cost.
