Help Imad patch the roof before the autumn rains

I'm a school janitor living in Jeddah. During the last storm water started coming through the ceiling in 4 places, and the kids' bedroom is no longer usable. A roofer quoted $1,500, 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 a small crew who can help over one long weekend. 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. Thank you for reading my story.
