Seeking Part Time Transportation For Middle Aged Adult

I am an individual with a disability who requires transportation from my home to downtown Chattanooga so that I can volunteer. I need picked up near the Catoosa / Walker County line. This is trial basis: if the arrangement works out, I may arrange more trips. I believe at the moment this would be a primarily morning trip; but, late mornings might be a possibility. I just don't know at the moment.. My ideal person must be female and comfortable with driving in downtown Chattanooga, as well as driving the freeway. Willing to discuss pay for time and gas.
