We could not give an estimated price as this would depend a lot on what kind of work you need, but there are many options to choose from. For example, Vanessa Hall and Joseph Jones are good photographers for weddings, events, or just to have a mement of your time on the island. If you need something more specific, like yacht photography, AcquaFilms is a great option in Antigua.
