Companion Care Needed

I need a companion care provider for my mother who is in her 80s, has dementia. My mother is super easy, sweet, walks on her own (holding onto walls), does her personal business on her own, just needs someone to be here to feel she is safe, prep breakfast and dinner (microwave frozen meals) and put TV shows on for her. I am looking for someone every Tuesday afternoon 3-6 p.m. Additionally, Tuesdays and Wednesdays 2x a month hours 8:30am-6 p.m. This role will most likely grow to a live-in role within the next 6 months if that could be of interest. Non-smoker and comfortable with pets.
