Henrique needs my school-run minibus repaired to get back to work in São Paulo

I make my living with my school-run minibus. 12 weeks ago the fuel pump failed, and the mechanic says the repair will cost $500. Without the vehicle I earn nothing. I have been borrowing from friends to pay rent, and now I have run out of people to ask. I support my two daughters and my mother. Before the breakdown I worked ten hours a day, six days a week. I have been offered extra shifts for the next three months if I can just get the vehicle working. I have a written estimate from a certified mechanic and will upload it here. All money will go toward the parts and labor on the estimate, with a small amount for road tax and insurance renewal. Where the $500 goes: • fuel pump replacement (parts): $350 • Labor charges: $70 • Road tax and insurance renewal: $40 • Towing and inspection: $40 Thanks for being kind about this. - Henrique
