NGOs pay developers and contractors all the time. They just don't pay very well, but nowhere does it say that work for them is free. Do as you wish. You can either donate your time, if you like the cause and can afford it. Or you can charge them a reasonable fee. Non-profit means that the organization's goal is not to turn a profit and give it to its shareholders. But a non-profit will pay salary to its staff and CEO if it can.
