A home for Lydia

My friends, this is a home in Grand Riviere du Nord, Haiti. Home to a young mother Lydia, and her 4 children, one just 4 months old. We will visit her next month, just 3 of us, and we want to help her. The best way we can help is to buy blocks to start making a better home. Enough to build a small one room block house is about $1500, and another $500 for a roof. She lives way off any road, part way into a mountain, and we will have to pay to transport materials too. Please help us to build her a safer home that the rain won't wash through for her and her children. One solid room would be a huge help, and a couple more rooms can be added later.
