Joe,
Try Pete Field @ Fields Guide Service, 503-539-0587 or 503-738-3481,
pete@deschutesriverguides.com. He's a good friend of mine and a really nice person. If he can't fix you up, he'll point you in the right direction. His specialty is running jet boat trips up from the mouth and fishing spey rods for steelhead. Although he also runs drift boat trips too.
