Seeking Part-time Senior Companionship Provider In East Lansing

I'm looking for someone to go to my 81-year-old mom's house 2-3 times a week to go walking in her neighborhood with her and probably stay and have lunch and chat with her. Physically she can walk unassisted but she has fallen a couple times in the last few years and has lost her confidence to get out and exercise without someone accompanying her. I don't live in town but my sister does and spends a lot of time with her but I think it would be good for both of them to have someone else my mom could have.
