Companion Care Needed

I need a hands-on care provider for my 89-year-old father who has mobility issues. He is very structured in his daily and weekly activities and we hope we find someone with patience (change is hard for my dad) and a sense of humor. We would like someone who can spend a few hours on Friday's doing grocery shopping, laundry and changing bed sheets . The job could possibly expand to additional days as needed in the future. We would also like some help with errands when appropriate. Preferences for a caregiver who is a non-smoker and CPR / first-aid trained.
