Help Amparo replace the engine head gasket and return to work

I make my living with my taxi. 10 weeks ago the engine head gasket failed, and the mechanic says the repair will cost $350. 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 eleven 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. I'll pay the mechanic directly and show you the repaired vehicle in an update. Where the $350 goes: • Road tax and insurance renewal: $50 • Labor charges: $70 • engine head gasket replacement (parts): $230 Thanks for being kind about this. - Amparo
