Hands-on Care Needed For My Mother In Nashville

I'm looking for hands-on care for my mother aged 88. Short term memory loss, so medication management is helpful. Complete assistance needed with bathing (I would like a 3X week bathing schedule) and dressing for the day. She has limited mobility and will need assistance walking and toileting. Some mornings may require helping prepare breakfast, not always. The ideal situation is to have a caregiver for two hours in the morning and two hours in the evening for bedtime assistance. I would like the same caregiver for both mornings and evenings but realize split shifts are difficult, so I am open to more than one. Preferences for a caregiver who is a non-smoker.
