Help Puerto Rico

My dear friends Neil and Miosotis are coming to live with my husband, son and I in St. Louis Missouri. They are victims of hurricane Maria and have accepted the opportunity to come to the United States for a better life for them and their daughter. The biggest challenge we are facing right now is funding their plane tickets out of the island of Puerto Rico and to the United States.  Anything any of you can do to help will be greatly appreciated. These are good people that are just trying to survive.
