Wheelchair van for Ciaran

Hello, thank you for visiting my site. My son Ciaran has a rare, catastrophic epilepsy syndrome. He has seizures nearly everyday and sometimes many a day. Ciaran had the left half of his brain entirely removed at age 2. Ciaran is diapered, tube fed and requires a wheelchair. He is 14 years old and getting big! Currently we are lifting him in and out if the car. I can no longer lift him since my back surgery. My husband can still lift Ciaran but it is getting harder. We really need a wheelchair accessible van but the cost is prohibitive. These vehicles range from $30,000-$55,000. Thank you for considering us!
