Roofing help wanted: Marcos's home in Mar del Plata

I'm a retired bus driver living in Mar del Plata. During the last storm water started coming through the ceiling in 2 places, and the living room is no longer usable. A roofer quoted $1,100, 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 anyone handy 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 to be comfortable with heights or willing to help from the ground. 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. You're what makes this possible, and I'll never forget it.
