Need a raft rental company suggestion for rafting the Upper Skagit in Washington

I want to take my family on the Upper Skagit this Summer as a Christmas present for my father-in-law (avid rafter with lots of Class IV experience), but I'm having a heckuva time finding a raft rental company anywhere close. Does anyone know of a good place to rent a whitewater raft near the Upper Skagit River in Washington? As far as I can tell, the nearest place is up the Skykomish in Index.

Alternatively, does anyone in the Seattle/Everett metro area have a raft they'd be willing to...
