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

I make my living with my delivery van. 5 weeks ago the radiator and cooling system 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 family of five. 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. 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: • Labor charges: $55 • radiator and cooling system replacement (parts): $75 • Towing and inspection: $20 Please ask me anything in the questions section. I'll answer honestly and quickly.
