Donate 600$ for a disabled girl

Hello, I am in need for a donation of 600$ for a little disabled teenage girl who is 15 years old. She has the condition knows as "Cerebral Palsy" and cannot walk without walker. (Google it for more info). She is in need of a walking walker which is approximately 600$. If you could donate 600$ to the child it would be really great for the help. Here is the link to the walker http://www.especialneeds.com/kaye-swivel-front-wheeled-wide-posture-control-walkers.html
