In-ho needs my ride-share car repaired to get back to work in Incheon

I make my living with my ride-share car. 3 weeks ago the engine head gasket failed, and the mechanic says the repair will cost $800. 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 wife and our newborn. Before the breakdown I worked ten hours a day, six days a week. I have been offered extra shifts for the next four 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 $800 goes: • engine head gasket replacement (parts): $510 • Road tax and insurance renewal: $100 • Labor charges: $190 I'll pay this kindness forward the moment I'm able to. - In-ho
