If you're looking for a guide service, there are two that work that area.
agua AZUL Whitewater Kayaking in Mexico
is run by Grant Amaral - I've always ran my own trips, but I have had friends go on his guided trips and they had a blast. His camp is right at the base of Micos, too.
I think that Andria & Leland Davis run a program too - It might be just for women, though.
