Help Kollasch family after house was destroyed

My name is Mark Kollasch, I live in Burien, Washington with my wife and five year old son. On memorial day this year, A person was driving an estimated one hundred miles an hour and crashed into our house making it completely unlivable. Thankfully nobody was home other than our dog and she escaped harm. The car actually went straight through our house and hit our neighbor's house as well. Any help would be appreciated while we try to figure out what's next for us.
