I don't know if they have any openings however I see your "home 20" is Everett so the Skykomish would be your most convenient best bet, try calling:

Sam Ingram: 360-435-9911
Rod Bush: 206-367-0514
Rob Endsley: WWW.kulshanexcursions.com
Cal Stocking: 360-428-0538

You and your dad would be happy with any of these guides. Sam is stricly driftboat, the other three can do sled or driftboat. Your best bet would probably be a mid-week booking (less traffic) sidedrifting in a sled; however Sam is an expert on the Sky backtrolling bait for hatchery steelhead and summer chinook.
