Help rebuild our home

I never thought I would do one of these or have to do one of these, but, as everyone knows we had some bad flooding in Houston the past few days. My house has been one of them. Spring creek overflowed into my neighborhood and brought four feet of water into my home and it's still rising. We grabbed what was important but lost everything else. Our home is destroyed and we have to start over from scratch to rebuild it from the floors up. I would appreciate any help at all and I will be eternally grateful. It is a truly devastating time for myself and my family.
