Volunteers needed to fix a leaking roof for Gopal in Hyderabad

I'm a single mother of three living in Hyderabad. During the last storm water started coming through the ceiling in 3 places, and the living room is no longer usable. A roofer quoted $690, 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 two Saturdays. Experience helps, but it isn't essential - I'll have a licensed roofer supervising for safety. All you need is sturdy shoes, gloves and a willingness to work. 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. Even a small gift gets used right away and I'll thank you myself.
