Companion Care Needed - Full-time / Part-time

Our family is looking for a kind person to come and sit with our mom who has Alzheimer's and be a companion. We would really like someone that would be an extension of our family and help when dad needs a break. She cannot communicate in full sentences anymore but is physically very capable. She is still very with it even though her ability to communicate is not great. We would hope to have this person meet her and become a friend. Eventually may need help with hygiene (showering, etc) but we are not there yet.
