Help transferring our little boy!

Hi my name is Kate Mansbridge, I am Liam Mansbridge’s mother. We are trying to raise some money for the Turny Evo Swivel Seat for our van to help transport Liam to doctors appointments. It is an adaptive remote chair that makes it easier transferring him, aiding in unloading and loading. He is a growing boy, he is extremely tall for a 7 year old boy, he is 4”5. Loading him in the car with 2 people is getting to be impractical. Not only would this help out us, it will be more comfortable for him as well because it stresses him out and hurts him being carried. Anything would help and be gratefully appreciated! Please share!
