Help my sister

As many in Houston, my sister's house got flooded, 2 days after being rescued they were able to get back to see their house destroyed by the water and their 2 cars along with it. As they started the cleaning process, trying to cope with their reality, they found out they, as many others, did not have flood insurance. Many have offered to help, hope those were not empty words, please show us you meant it. They need financial help to clean what's left of their house; replace everything they owned from clothes to appliances, and cars; they need a place to live and rebuild their house.
