teach overseas in a wheelchair

hello out there, this is an enquiry and I wonder if anyone out there can help me. I have one student who is in a wheelchair who would like to teach English either China or Vietnam with his friend. He's a trained teacher and just about to do the TESOL with us. Can anyone suggest a school that they can both work at that is on the flat! And accommodation has to be ground floor also.
Your help is most appreciated! Gabrielle from NZ
