If I were in your shoes, I would focus efforts on NE Washington. Western Washington isn't even managed for turkey anymore as far as I recall. I think they cancelled it because they realized the Easterns just weren't taking.
Unless you have access to land that holds wild turkey, or know of a few flocks in your local area, I think you may end up being frustrated in your search.
The closer option for you may be the Klickitat area. It's good, but nothing will beat NE WA.
