Companion Care Needed For My Mother In Miami

I'm looking for somebody to help out my mother. She is 84 years old and blind. She lives with me and my wife and kids, but we have too much going on and she is bored out of her mind. So we need somebody that will take her places, out shopping, whatever, and help her find her way around. She will sometimes also need help doing tasks around the house, and help preparing simple meals. We may also ask for some light housekeeping when she is resting or not doing anything; doing dishes and picking things up, but not too much. She does not speak Spanish and she is hard of hearing, so we need somebody that speaks good English. Must have a valid driver license. We can start with 2 or 3 days a week. We're flexible on which days as long as there is some gap between them. Depending on how it goes, there might be opportunity to work additional days.
