Aiden needs my school-run minibus repaired to get back to work in San Diego

I make my living with my school-run minibus. 3 weeks ago the engine head gasket failed, and the mechanic says the repair will cost $900. 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 family of five. Before the breakdown I worked ten hours a day, six days a week. I have been offered extra shifts for the next six 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 $900 goes: • engine head gasket replacement (parts): $520 • Towing and inspection: $125 • Labor charges: $255 Ask me anything below before you decide. I'd rather you were sure. - Aiden
