There have been some good suggestion submitted. There must be many other options to consider or create with his experience and knowledge of the territory. Do you live in the London area? I would research other driving services being advertised to stimulate your thinking. I agree with others that this pandemic must be creating a need for local travel support. Keep looking at related services such as a store that need drivers to deliver packages, etc. I feel you can create an opportunity for a driving service in some form. Also, I suggest he talk with fellow taxi drivers who have lost work as well and see if they have uncovered opportunities. Good luck and keep us informed.
