Companion Care Needed For My Mother In Arlington

I am looking for help for my mom for 7 days a weeks around lunchtime (10:30-12:30) for 2 hours a day. Mostly, this is to help with lunch and companionship. On weekends, I might also need a person in the late afternoon (3-7). If you can just do during the week - that's fine or if you can do just weekends that's also fine. This is for a limited time - mid- January through end of February.
