Gas fitter needed urgently: Jade's home isn't safe

In July an inspector told me that my home has a failed boiler with no heating. It's a safety risk for me and my three children. The landlord has refused to act, and quotes of $1,950 are beyond us. I'm looking for a licensed gas fitter who may be able to donate a few hours or do the repair at cost. I can cover the parts, which I estimate at $250. 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 gas fitter 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.
