My delivery van: Katherine's only way to earn a living

I make my living with my delivery van. 6 weeks ago the gearbox failed, and the mechanic says the repair will cost $1,300. 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 eleven hours a day, six days a week. I have been offered extra shifts for the next six 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 $1,300 goes: • gearbox replacement (parts): $710 • Labor charges: $220 • Road tax and insurance renewal: $280 • Towing and inspection: $90 Thank you so much.
