Looking for a room in exchange for housekeeping or caretaking (Margate to West Palm Beach)

Mature female looking for a room in exchange for housekeeping, elderly companionship or helping someone recuperating from an illness or injury.
Flexibility to otherwise work.
Can be short term.
I also do organizing, computer work, painting etc.
I'm honest, respectful and responsible.
I don't smoke or drink.
Prefer senior female roommate.
Just looking for a clean, quiet, safe environment in exchange for helping someone and getting on with life.
Thanks.
