Dave, sorry to hear about this mate, I know what it feels like, and some times it would be nice to have some reasonable comments on what to do next. Silly comments IMO dont help anyone who is in this situation.
Have you thought about marine Valet? I have been told by a friend, who is in the business that there is plenty of work in that field, although I would imagine it would be loads harder than a car.
How are you with a set of spanners? Mobile mechanic?
Setup your own property maintenance company as you are already in the business
I am sure that with you excellent charm and charisma, you will be able to turn your hand to anything.
Keep in touch mate, must catch up again
