Fishing Partners in PDX?

Hey all, this is Béla (Yakky Doodle) -- I've been absent from this forum for a couple of years, but I'm getting the fever to hook some fishies.
I've got all the gear and kayaks (cobra tandem - I use this for crabbing) and an OK Prowler, but alas, I don't know much about catching big fish.
Whenever y'all want to take this newbie dude out on the Willamette, lemme know. I live in L.O. and am free most weekdays.
Thanks!
