So many places to start. Maybe check with the local Goodwill to see if they can give any leads. Next might be the local building inspector's office to get guidelines on locating equipment controls so they can be accessed from a wheel chair. (One experience involved a building being set up for a commercial application was with the thermostats being located too high for a wheelchair user.)

Next would be possibly with the state our county employment office. Maybe they can offer leads on organizations of interest to your plans.

Good for you on trying to help those who mostly look forward to helping themselves.
