Companion Care Needed

My mother is a fun, lively senior who's currently living independently in Hamburg. She is very social and enjoys painting and gardening. She has been diagnosed with Alzheimers and is beginning to need more care. We are looking for a companion to help with driving her to unfamiliar places, assisting with medications, driving to doctors' appointments and conferencing us in, preparing meals a few times per week, and generally helping my mom stay as social and independent as possible, with trips to the art museum or other outings. We prefer a non-smoker who owns reliable transportation. Right now the schedule would be 4 times per week for a half day each time.
