Grab a couple of these. Roberts Ranger lures, made at Marthas Vineyard.
Swap the hooks and split ring for a heavier duty hook and splitring.
As far as a boat goes, look up Capt Lora or Chuy out of Punta Mita. Which is about a 10 min drive south of Sayulita.
Lita is a great spot, its a booming spot for the younger crowds, surfers mainly.
