Help Yun-seo patch the roof before the next storm

I'm a single mother of three living in Seoul. During the last storm water started coming through the ceiling in 4 places, and the kids' bedroom is no longer usable. A roofer quoted $1,950, which isn't something I can pay. The good news: a local hardware store has donated the shingles and underlay. 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 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. Whatever you can give, even just sharing this page, means a lot.
