Hi Florian - youve got to go down the web based route - try one of the multilistings site with good search rankins - i shouldnt advertise but im involved with Caribbean Homes & Lifetsyle magazine from Antigua and we are doing a lot of work on our webportal caribbeanhotproperty- we dont current list VI but will be expanding west in the next few months - if you require futher info let me know.

Alterntively i would recommend a combination of High Quality Artciles in one of the larger real estate mags - get some int exposure in the country that the majority of vistors are coming - as for radio its a bit hit or miss

hope this helps a little - chris
