My motorbike: Sarah's only way to earn a living

I make my living with my motorbike. 7 weeks ago the engine head gasket failed, and the mechanic says the repair will cost $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 ten 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 $300 goes: • Labor charges: $60 • Towing and inspection: $25 • engine head gasket replacement (parts): $215 Thanks for being kind about this.
