Seeking Part-time Senior Care Provider In San Francisco

I need a part time in-home senior care provider for my mother, who is 88. She needs a walker and has some short-term memory difficulty but is otherwise healthy. Looking for a caring companion fluent in English. Help needed with bathing once a week. Help needed with groceries or laundry on some days. Most days just needs cheering up and reminders . At the moment 8 hours a week is enough, but this will increase over time as she gets older.
