Hunter's motorized wheelchair

My son Hunter has hemophilia B with inhibitors. Till now he has done well using a wheel chair when he had a bleed in his ankles. Unfortunately, his elbows are no longer able to stand up to pushing his chair. This school year has been a tough one. His ankle bleeds have become frequent. When he goes to school in his wheel chair, he ends up with a bleed in his elbow. A motorized wheelchair would help Hunter to attend school more often and limit painful bleeds. The requested amount is for the motorized chair and a lift that mounts to the car. Thank you for your time.
