Chartered fishing trip and other activity recommendation.

We are staying for two weeks in Chacala at the end of February 2018. My son (age 8) and my husband want to do a guided fishing trip. Any recommendations for contacts to do this activity? This is our first trip to Chacala and we love adventure. Any other suggestions for activities in the area or day trips we should consider? We are renting a car so transportation is not a problem. We will also have a 6 year old and 17 year old with us.
