Looking for cheap car - $3,000 (San Bernardino)

I am desperately in need of a car.
I have been taking the bus to work for years and it is not reliable enough.
I am very low on cash because of bills that I have been paying for medical costs of close family.
The thing is this.
I am looking for a generous individual that would accept services in exchange for a vehicle.
I have substance and I have skills that can be utilized.
I can help you out ongoing if you wish to have continued servicing.
