Companion for Jade while I'm at work, Los Angeles

I'm Liam, and I look after my mother at home in Los Angeles. Jade has a weak heart and should not be alone for long stretches. I work early shifts, and the gap on weekday afternoons is the hardest part of my week. What I need is someone calm and reliable to be in the house from about 1pm until 5.30. Mostly that means company, a cup of tea, lunch and a short walk if the weather is kind. No lifting and no medical care. Jade loves the radio and will talk your ear off about it. I'm home before dark and will always leave the phone numbers of the doctor and a neighbor. I'd like to meet you first with Jade present, and I'm happy to give a reference from the parish. If you have done care work before, wonderful, but kindness matters more. I'll be so grateful for any help at all.
