Companion Care Needed

I need a companion care provider for my husband in his 70s. Seeking someone to handle meal preparation. Looking for a caring and compassionate companion. Preferences for caregiver who is comfortable with pets. He is ambulatory with walker, need someone to oversee that he does not get off balance and fall. My scheduled days and hours change from week to week, days which I need someone will average around 6 hours per day, maybe two days a week.
