As far as wedding help, can you give us an idea of what part of the DR you're thinking about having the wedding in? How many people? Do you want site suggestions, or do you want the names of wedding planners?
I did a quick search on wedding planner, and here's the link. The search function (upper right hand side) can be tricky, but if you play around with it you can usually get some results. As others have said, the more specific you can be, the better information you'll get.
You can also see hotel and resort websites once you know what area(s) you are interested in..many offer information on their packages, pricing and capabilities
