Charlie’s chair

I'm hoping to raise some money for my son so he can have a wheelchair. He is called Charlie. He is 8 years old and has cerebral palsy, global developmental delay and cerebral visual impairment. I would love to buy him his very own wheelchair that suits his wonderful amazing personality. We do have an nhs pram but he is growing at lightning speed and will have grown out of it soon and as he's almost 9, i want him to feel older in a proper wheelchair instead of feeling like a baby in a pram. please could you help get the most amazing boy I know have independence and feel like a growing boy? Thank you all so so much
