Lots of folks mentioned SWA. The other group that runs trips that might take you on as an assistant guide is AdventureKayaking.com
Mary and Phil DeReimer run kayak trips with clients from Rio Quijos down to Tena and they might have some info.
Write quick, they are headed to Bhutan.
You might be looking for paddle boat gigs, but they obviously know the score down there.
