Help Diệp with an electrician's skills: a burst pipe behind the wall

In August an inspector told me that my home has a burst pipe behind the wall. It's a safety risk for me and my newborn. The landlord has refused to act, and quotes of $410 are beyond us. I'm looking for a licensed electrician who may be able to donate a few hours or do the repair at cost. I can cover the parts, which I estimate at $15. 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 an electrician and can help, or know a program that assists with this sort of repair, I'd really appreciate it. Please ask me anything in the questions section. I'll answer honestly and quickly.
