Companion Care Needed - Full-time / Part-time

I need senior care provider to assist my 77-year-old mom and dad with some light Housekeeping, Errands / Shopping, Transportation. We would prefer someone who can help change their cat's litter box. We might ask you to run errands now and then. We ask that you handle transportation as needed. Looking for a few hours once a week with the possibility of greater hours if their needs increase (though also open to multiple helpers for different days as scheduling requires). Mom has mild dementia but is quite independent, dad has recently undergone surgery for a brain tumor and has some cognitive deficits that we are continuing to learn about as it unfolds.
