TBI survivors - has anyone employed a driver?

If so, any advice you can give me?
Buses in the UK are limited and restrictive. It is possible to get to places in the day but impossible to get back from a big town at night.

I suggested going somewhere (which needed a car) with a friend and her immediate response was 'you don't drive do you.'

I do not'use' my friends as a taxi service so am gonna employ some-one. Does anyone else have experience of doing this?
What do they charge?
Do you know who I could approach.
I have contacted Headway (British Brain Injury support organisation). If anyone else in England can recommmend / suggest anything I'd be grateful.
