I don't know what your field of study is but I'd look into working at group homes or being the "base" instead of the driver? If you can get a ride/take a bus to work in the morning and home in the evening, that would be okay I'd think. You can't work something out so you and clients could take the bus/public transportation? The City does not have smaller handicapped buses of some sort your agency could request so you all could still get to/from a central location?
