Hi Jim,
What a well written message.
My Dad is in the same situation as you. I know how difficult simple tasks, to me, can represent challenges to many others.
I cannot answer either of your two questions.
But I can offer this...
I am a member of the car club called Zipcar.
I can hire numerous cars and vans from as little as £5 or £6 an hour (including fuel and insurance). Many of them are lurking around the hill.
I also have plenty of time on my hands.
We could hook up and start our own social enterprise!
We would have to look at the legal side and I have access to good local legal eagles.
Maybe we could meet and explore?
Kind Regards,
Rob
P.S. I just realised that I have actually answered your question 2. Hence, this P.S./edit.
