Help Jose replace the gearbox and return to work

I make my living with my food truck. 3 weeks ago the gearbox failed, and the mechanic says the repair will cost $2,000. 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 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 $2,000 goes: • gearbox replacement (parts): $1,200 • Labor charges: $410 • Road tax and insurance renewal: $260 • Towing and inspection: $130 Please ask me anything in the questions section. I'll answer honestly and quickly. - Jose
