Companion Care Needed

My mother is in her early 90s and has severe arthritis in her legs. She is 100% there mentally. She is seeking part-time assistance on weekdays in the morning - early afternoon (somewhat flexible on days / time). She needs help with meal preparation, light housekeeping, bathing, occasional errands and transportation (for medical appts). She uses a walker, but is sometimes unsteady. She dresses herself, but could use assistance getting her clothes ready. She has no pets. My brother and I (and children) visit her regularly, but cannot be there during the daytime due to work and school.
