Respite care wanted: a few hours a week with Renata in São Paulo

I'm Sérgio, and I look after my sister at home in São Paulo. Renata has poor mobility after a hip operation and should not be alone for long stretches. I work part-time at the shop, 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 12.30 until 5pm. Mostly that means company, a cup of tea, lunch and a short walk if the weather is kind. No lifting and no medical care. Renata loves crosswords 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 Renata present, and I'm happy to give a reference from my employer. 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.
