Work Vehicle

Divorced single parent household. self employed contractor. Work as much as I can to raise my son along with paying for his car that is need of repair as well.  Recently my work truck has a blown engine and found it is going to cost near 15,000 to repair the motor for replacement. This truck is what helps me work in order to pay for my son's needs and our every day life expenses. also what gets me to his games to watch and support him. I've been going around trying to get friends for rides along with help getting materials to job sites.  I don't get much help from the mother other than what is court ordered. Not looking for my everyday life expenses to be paid for just trying to get help with getting truck back on road.  I am also trying to come up the money by selling my dream classic car that I recently purchased to help fund this repair.  any help is appreciated. Just a father trying to provide.
