Rides to dialysis three times a week for Wellington in São Paulo

Wellington has been on dialysis for 2 years and until recently drove to the São Paulo Dialysis Unit alone. After a foot amputation, Wellington can no longer drive. Taxis cost more than the family can pay three times a week. We're building a rota of volunteer drivers. Each session is 4 hours, including the trip there and back; most volunteers take one regular day. The journey is about 19 km each way. Wellington is cheerful company. You'd need a car in good condition and a clean driving record. We'll cover your fuel costs, and the family will send you home with homemade food. Please say which day works for you in the comments. I hope life is good to you.
