Me?
I have been involved in my own time with a recycling project for about 6 years now on top of just the stuff we all learn along a way if we are keen enough, I turned down a mechanics job with one of the UK fabricators as it wasn't enough money, of course I don't feel the need to go on about this all the time and claim it as a position of authority as I am not an arrogant prick who uses it a stick to beat people with all the time - you trying to call people out on things like that all the time is rather odd.
I also know several other guys who have tried the mobile mechanic thing and it's been a hiding to nothing as a stand alone business without an existing customer base and workshop to operate from, or you find someone with more money to throw at it as vanity project will undercut you and make it not worth your while as my mate Ant found in Sheffield. Maybe in some areas if there is enough disposable income floating around it might work - but that's the exception and not the rule when it comes to the rest of the UK.
I am not sure what your problem is here, this is not P&L and no one is getting at you so I think you need to calm down a bit.
