Paul Dixon is the top rod out there.
if he's not free (or any of his guys) i know former guide Amanda Switzer recommended Ernie French or Jim Levinson.
I hear good things about David Blinken too.
It would help if you can be flexible on your dates, typically the best guides up there will be booked up 9 months in advance. They might have a vacancy here and there but thats primetime for the 'zoo' up there.
Amanda is sadly retired now, but she was respected as one of the best, but those guys are very fishy - if the fish are around they'll find them if the seas permit.
best of luck.
Mark.
