Mechanic Job in Portsmouth, Virginia

I recently bought a 1990 Ford Taurus wagon. I was told the radiator needs replaced. I've been adding water to the resevour for last week. I do t drive far so usually just once prior to trip is sufficient. I am a single mom I don't have much money and I only paid 400$ for the car so I'm really not looking to spend an arm and leg to have it repaired like an auto shop may charge. But I do want to keep the car in good condition so i would like to have it checked and possibly repaired if affordable.
