wheelchair van 4 my son

Champie is a 26 weaker we lived at Riley Nicu for 3 months. He has Pvl cp autism and adhd. He is in a wheelchair he is now 7 years old and is 4'5.5" tall and weighs 122lbs and he will soon be getting a power chair. On Jan 18 my mini van got hit and they Totaled it out so right now I am without a ride I really really truly need this Van for my son so we can transport him safely he is just getting so big it's hard to pick him up and put his wheelchair in the Van and/or vehicle .right now we're without one so any help at all would be very gratefully appreciated.
