Plumber needed urgently: Frieda's home isn't safe

In September an inspector told me that my home has faulty wiring that trips the power and smells of burning. It's a safety risk for me and my two small children. The landlord has refused to act, and quotes of $780 are beyond us. I'm looking for a licensed plumber who may be able to donate a few hours or do the repair at cost. I can cover the parts, which I estimate at $135. The job should take about four hours. I'll make sure someone is home and will provide refreshments. I can share the inspector's written report on request. If you're a plumber and can help, or know a program that assists with this sort of repair, I'd really appreciate it. Thanks for being kind about this.
