Senior Caregiver - Full-time / Part-time

I am looking for senior care for my 89-year-old grandma. She typically can care for her self pretty well, but has days where she does get a little confused and needs additional help, mostly with meal prep and changing clothes. She is on oxygen concentrator and uses a walker to get around. Looking for someone who can come for an hour or two in the afternoons/early evenings (times are flexible) She has a great sense of humor so looking for someone that can joke around and giver her a good laugh and companionship.
