New wheelchair for my son

My son Nickalas is in need of a new wheelchair… Unfortunately his insurance company is not willing to help with the expense. He has been denied three times at this point and he is growing at a rapid pace and needs a larger chair to accommodate his growth spurt.  He has already been measured and we have picked out one that will fit him. I am in need of donations of any size to help him get the chair he so desperately needs thank you in advance for any help you can do …
