Help Mitu replace the engine head gasket and return to work

I make my living with my taxi. 8 weeks ago the engine head gasket failed, and the mechanic says the repair will cost $200. 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 nine 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 $200 goes: • engine head gasket replacement (parts): $130 • Labor charges: $30 • Road tax and insurance renewal: $20 • Towing and inspection: $20 Every share and every dollar helps. - Mitu
