Companion for Luiz while I'm at work, São Paulo

I'm Joaquim, and I look after my father at home in São Paulo. Luiz has failing eyesight and should not be alone for long stretches. I work long days at the clinic, 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 2pm until 6pm. Mostly that means company, a cup of tea, lunch and a short walk if the weather is kind. No lifting and no medical care. Luiz loves old films 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 Luiz present, and I'm happy to give a reference from the parish. If you have done care work before, wonderful, but kindness matters more. Thank you. A few hours from you would make a real difference to our week.
