I did mine with Trip Whacker (no joke) at Flagler County airport, a bit north of Ormond Beach & Daytona airports. He doesn't have a C180 amphib anymore and uses a Maule (I think) and a Beaver.
As best I remember it cost me about US$3000 for all training & testing (he also did the test).
<later>
Forgot to mention that I did mine in 2004. Prices are likely to be different now.
