5x7 film holder case - need help

The photobackpacker film holder cases for 4x5 and 8x10 are designed, prototyped and ready to go into production. I want to offer a 5x7 case but I need to find five 5x7 filmholders to test my design sample.

I will take extreme care with the holders and will need them for only 3 days or less before sending them back. I will pay the shipping each way and will give the owner a 5x7 film holder case out of the first production run (spring 2011).

Your help is greatly appreciated!

Two offers in less than an hour! Thanks!
