Help Cecilia with an electrician's skills: a leaking gas line

In December an inspector told me that my home has a leaking gas line. It's a safety risk for me and my two small children. The landlord has refused to act, and quotes of $390 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 $30. The job should take about three 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. I'll keep this page updated with receipts as things happen.
