Help Jun replace the gearbox and return to work

I make my living with my motorbike. 6 weeks ago the gearbox failed, and the mechanic says the repair will cost $255. 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 2 children. Before the breakdown I worked eleven 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 $255 goes: • gearbox replacement (parts): $165 • Labor charges: $55 • Road tax and insurance renewal: $30 • Towing and inspection: $5 Thank you so much.
