Companion Care Needed For My Mother In Los Angeles

Help needed for my mother ( late 60s) who has Alzheimer's. I'm looking for someone who can come to stay with her when I need to leave the house or to provide companionship during the day while I'm working from home. She enjoys coloring, crafts, playing Bananagrams, and watching tv. She also likes walking to the shops a couple blocks away (CVS, Vons). Please note this is NOT for full-time care. This is short-term/as-needed. Current needs: Can be flexible around your availability. This is mostly to provide her stimulation and give me a break. Future needs: Monday/Wednesday evenings 4 p.m. - 8pm, Feb - June.
