Help Lasanthi patch the roof before the autumn rains

I'm a home-care aide living in Colombo. During the last storm water started coming through the ceiling in 3 places, and the living room is no longer usable. A roofer quoted $470, which isn't something I can pay. The good news: a local hardware store has donated the corrugated iron sheets and timber. What I don't have is people to do the work. I'm looking for 4-6 people who can help over three weekday mornings. Experience helps, but it isn't essential - I'll have a licensed roofer supervising for safety. All you need is work boots and a hat. I'll provide lunch, water and lots of thanks. The work will be done on the ground and roof with proper harnesses. If you can only help for a few hours, that's welcome too. I hope life is good to you.
