Help for evie

Hi my name is Natalie and evie is my niece, as a family we don't ask for help but on this we need some. Evie had an accident in school which has caused her to loose the use of her her leg, she is in constant pain and need help to walk move, stand and cannot be left. She's 13 years of age she now needs a wheel chair to get around and although we have been pro active in trying to get her back in school etc. She needs ability type scooter, now remember she's 13 we would like to get her something that she use by herself without her being worried about what her peers think. I would like your help if possible.
