Nick the easiest way is set up a processor and do it yourself at home. I shoot odd sizes that no one here will process so I do them myself. Once you're up and running any exotic size makes no difference and you can process any time you want, day or night.

Do you have an 11x14 camera? I think I have a box of Efke not doing much, I bought it to cut down but now have the proper size film for my camera.
