I have a property in The Dominican Republic I want to rent out by the week?

The property is in the resort town of Bavaro (Punta Cana). The home is paid off and seldom used. I want this property to start making money for me. Those of you with experience in renting out your properties as vacation rentals please give me any advice, suggestions and or comments on how to do this. If you can suggest any agencies or websites I would appreciate it!
