Companion Care Needed For My Mother In Venice

I'm looking for companion care for my mother in her 80s. Some light tidying up is involved. We're looking for someone to assist her with a few things. Duties include transportation (doctor's appointments, especially when further away, raining, or dark etc.) and cleaning - running the vacuum or hosing down the small porch. Also, she could use some technical help with her computer (getting something to print, replying to an email, basic computer knowledge would be fine). Prefer a caregiver who is a non-smoker. Mom needs help resetting clocks when the time changes... just little things for the most part. For now, we would love someone to come once a week for two hour. This could be the same day or it could vary. Eventually, maybe it would be more on a call basis or time could be added. For now she really needs someone she can call if needed.
