Two weekends of roof repair for Dhanush, a night-shift nurse in Kolkata

I'm a night-shift nurse living in Kolkata. During the last storm water started coming through the ceiling in 4 places, and the bathroom is no longer usable. A roofer quoted $610, which isn't something I can pay. The good news: a local hardware store has donated the roofing sheets and nails. What I don't have is people to do the work. I'm looking for three or four volunteers 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. I never thought I'd be the one asking, and I'm grateful for every bit of support.
