Sink Farm

Can anyone give me an idea of the cost of refinishing an old porcelain farm sink four inch deep and 30 inches wide?
Sink also has a 30 "by 15" backsplash. Just wondering if anyone could approximate the cost or ask someone you know. Thanks Dana
methods miracle loads of about 350 for a bathroom in the house. If you find someone and give it to them, must be about 100.
