Hey,
I used to fly on Curacao for the Police Department, but that is already some moons ago. I went throught the internet search engines but "Pelican Air", the original helo service must have ceased operations some time ago because the only results I get is "domain builders". The only operator I know about is in St. Maarten.
Apparently a friend of mine got hooked on the R44 to fly for the police there. Speedykopter did not succeed in Curacao with a long term aerial law enforcement contract (we had problems with contract renewals in the pre-speedykopter era). Anyway, there also used to be "Colibri Helicopters" in Aruba. Some guy from Colorado tried to establish a service way back in 1999. Since I have not found any listings I assume this operation is also terminated.
Good luck in your search
