I have a few suggestions for rental agents you can call:
Luanne Nudi, 941-957-4677, Ext, 501, http://www.nudionthebeach.com/
Connie Nowell, 941-628-0949, www.RentMeFlorida.com
Brian Fischer, 239-225-5663, Douglas Realty, firstname.lastname@example.org
I think between the three of them they should be able to find something for you. Good luck with your search!
