Help Gabriel with a roofer's skills: faulty wiring that trips the power and smells of burning

In July 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 $660 are beyond us. I'm looking for a licensed roofer who may be able to donate a few hours or do the repair at cost. I can cover the parts, which I estimate at $90. The job should take about six 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 roofer and can help, or know a program that assists with this sort of repair, I'd really appreciate it. I'll keep this page updated with receipts as things happen.
