Help A Single Mom Repair Her Only Vehicle

I'm a struggling single mother in need of help with an unexpected vehicle repair. My motor and cam shaft need replacing and I currently do not have the funds to pay for it. Being a single mother is hard with paying everything on my own and waiting for child support. I'm just looking for some help, I need my vehicle fixed as it is my only vehicle. I have other bills that I have to pay with what I make working. This economy is tough right now.
