I highly recommend Photographics Maui. Great photographers; they provide so much more than the standard wedding shots. They really know how to direct the subjects so that the photos are full of life and love and fun.

As of just recently, you now have to have a permit to get married on a beach. Your wedding contacts here can help you with that, or call Maui County.
Big Beach in South Maui is used a lot for weddings, because of the gorgeous scenery and you can get photos with no people or structures in the background.
