Hurricane Harvey help for my cousin

My name is Candace Fry from Macon, GA.  My cousin, Grant Spelbrink, lives outside of Houston and is dealing with a flooded house from Hurricane Harvey.  How do I help my cousin, his wife, and son in a tangible way since I can't be there physically?  Money...that's what they really need to put their lives back together after Hurricane Harvey.  They were finally able to get back to their home and discovered 3 inches of water in the house...mud...and an awful smell.  This is what my cousin wrote when I asked him if I could try to raise money for them: "It is hard to swallow your pride and ask for help, but we are in a situation that requires us to accept all of the help that we can get.  I can promise that any money will be used wisely.  Thank you so much!"  Any amount will help!  They need bath towels, cleaning supplies of all kinds, repairs, furniture, food, and any other items that insurance will not cover. Prayers for all those dealing with the aftermath of Hurrican Harvey.
