looking to rent a beachfront house in Dec.

Have been searching through the Google ads and Thought I would try and put a post up here as well.
Looking to rent an oceanfront house in Florida(Gulf side) in December.Are there any other places to look for rentals besides google?
We are successful,honest, 32 yr old non-smokers,no kids and just looking to spend a week on the beach and relax.Have a waterfront house up here in WNY,but can't get much use out of it in the winter.I can provide a complete background check or whatever someone needs to rent one of these places.
It seems most are somewhat high-end so I was just trying to make someone feel safe.I know I could never rent my house out,but seems to be fairly common in Florida.
Thank you and if you know anyone that has something That may be suitable for us,or any other information please let me know.
