Companion Care Needed

About who needs care: He walks, but unsteadily. He tends to stay nauseous and eats small meals at a time. He needs help getting up and down, meals, getting into and out of shower, and taking medicine. He is a smoker, but will go on porch (with help) to smoke if it bothers the caregiver. We need help for a week, so we can go on vacation. About the care needs: He is a loner. He just wants the caregiver to do what they need, and leave him alone the majority of time. He really doesn't bother anyone, just needs a little help with daily tasks while we are away on vacation. Services needed include: meal preparation, errands / shopping, light housekeeping, feeding, and bathing / dressing.
