re: I need some electrician help

While there's a thread open I've got a question too.

Electrical breaker box on the outside of my home has rusted pretty badly and needs to be replaced. It's just a normal panel box with four fuses inside. I'm assuming since it is tied to the meter I need a registered electrician to replace it. How much should that run me for parts and labor? Also any recommendations in br?

Thanks in advance
