Seeking Part/Full-time Senior Care Provider In Venice

My mother and father in law are staying in their condo in Florida while they build a smaller home up by us and I need a care provider with experience with Alzheimer's and dementia. She is undiagnosed but there is apparent evidence of decline. I would like to be able to get a formal diagnosis but in the meantime we need someone to be at home with my mother as she has gotten to the point of needing companion care for her during day time and can no longer be left alone. Our concerns are - but may not include at all: Light Housekeeping, Help Staying Physically Active, Meal Preparation, Companionship. Please be willing to do light housekeeping but may not ever be required. Majors duties include providing companionship and social interaction. . Supervision mostly.
