Yes, you know, the more I've thought about it and researched it online, I would not offer to transport anyone in my car...too much risk involved. I would concentrate on Drop off/Pick Up services, Shopping services, etc.
I think offering this to retirement communities/apartment complexes would be good, too, because of the simple fact that elderly just might not be able to get out often. Prices would have to be adjusted due to fixed incomes.

The only thing that makes me a little hesitant is the safety factor - going into someone's home - you never know what people are thinking.
However, I still think this has great potential.

Thanks for your input!
