Help Ghada replace the gearbox and return to work

I make my living with my delivery van. 12 weeks ago the gearbox failed, and the mechanic says the repair will cost $150. 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 younger brothers and sisters. 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 $150 goes: • Road tax and insurance renewal: $45 • Towing and inspection: $10 • gearbox replacement (parts): $95 Thanks for reading all this.
