Help Roberto replace the engine head gasket and return to work

I make my living with my delivery van. 12 weeks ago the engine head gasket failed, and the mechanic says the repair will cost $400. 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. I'll pay the mechanic directly and show you the repaired vehicle in an update. Where the $400 goes: • Road tax and insurance renewal: $40 • Labor charges: $85 • engine head gasket replacement (parts): $275 Ask me anything below before you decide. I'd rather you were sure. - Roberto
