Help get Oli his own wheelchair rugby chair pls

Hello, I’m trying to raise funds to purchase a wheelchair rugby chair for Oli. He has been playing for over a year now using a club chair which is not ideal for him. Having his own chair will add comfort and more agility which will aid Oli in becoming a better player which should enable him to start playing competitively. Any help would be massively appreciated by Oli and myself. We have part funding from a charity called Caudwell but need this extra funding to complete the purchase of the chair.
