I dealt with them briefly when I was a college intern with Evergreen Helicopters in OR.

We were working with them setting up Evergreens Unmanned Services division. They were a small company but they seemed to enjoy what they were doing. They really liked the Scan Eagle and seemed to have good management and direction. If you can get a foot in the door, and UAV ops seems to be a good way you want to go, I would say give them a try.

If you are open to the east coast part of the US I would also recommend Aurora Flight Science. They do some good stuff and they also have some full size company planes that you may be able to help out in.
