House Sitter in Apalachicola, Florida

I am needing to relocate in the next few weeks from Tennessee to the Apalachicola area, and am in urgent need of free/low-cost housing. I would be interested in speaking to anyone there who may have a short- or long- term such opportunity available for me which would provide housing in exchange for watching and providing basic upkeep of the home. I have no pets and would prefer a place with no pet-care responsibilities, but based on the overall situation I would not rule it out for that alone. I am a single, 56 year-old professional woman who is very mature and responsible. I am in good health and can do basic housekeeping and yard maintenance chores.
