Caregiver Needed

I need a hands-on care provider for my wife in her 80s. Duties include providing companionship and social interaction. I need someone to stay with my wife when I need to go grocery shopping and to my doctors appointments( 8 to 16 hours per week). I have an appointment in Longview on November 10th at 10 a.m. and need someone for that day and one to two week days each week thereafter. It can be any days of the week. Preferences for a caregiver who is a non-smoker.
