Possible Freediving trip Aug 29th

Hi, I'm a 30M about to go on a trip to West Palm Beach around August 29th to September 1st, I was interested in freediving the inter coastal waterways around the blue heron bridge, peanut island, some of the inlets, and catos bridge. I was wondering about the possibility of meeting some other local freedivers who'd be interested in some casual diving so I'd have a good safety partner when I go. My uncle is also likely coming on the trip, he's a certified scuba dive master, but he does not do breath hold diving (yet 😉) and he also has likely obstructed eustachian tubes preventing him from equalizing well.
