If money is not an issue, a charter with some friends during snapper season.
But since money is almost always an issue:
A charter cost minimum of $150-200 for a decent 8-10 hour trip (don't mess with a 6 trip, that is 4 hours of riding and 2 hours of fishing), plus tip & fish cleaning, you are looking at $250, easily.
I can fish inshore from my boat and fish the pier all season for $250.00, and that includes bait and gas plus I am in control.
