Help Hiếu replace the gearbox and return to work

I make my living with my food truck. 4 weeks ago the gearbox failed, and the mechanic says the repair will cost $250. 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 4 children. 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 $250 goes: • gearbox replacement (parts): $200 • Road tax and insurance renewal: $20 • Towing and inspection: $30 Every share and every dollar helps. - Hiếu
