Airline Ticket Daughter From Argentina

My daughter in Argentina is going thru a Divorce after 17 years of marriage and needs to come back to USA to work and save money to get her two children/my grandchildren ages 15 and 12 home after the divorce is final. She has been unable to work after her ex-husband put her out on the streets and took her work away (family business) given her no money or support. He even hast just reciently let her see her own children. Because of her accent and being American she has not been able to work or save money. What work she has done has not even able to pay rent and very little food. Her husband's Family has not given her any support or even offered to help her. As the economy is so bad and inflation so high in Argentina it makes it hard to save money for any anything and impossible an Airline ticket ($1,000). Her mother, my wife just passed away on January 22, 2019 and she was not even able to come home for the funeral beause she had no current passport.  She has her passport now and is ready to come home.  I wish I could finance her ticket but I have been disabled for 3 years ( had a stroke) and so soon after my wife's passing and those expenses is why I am seeking help to get her home.  I have not seen my daughter in over 7 years and I cannot not travel beause of my paralyzed left side.
