I'd be quite happy at the pointy end of a twin prop taxi even if it was low-paid, etc.
That comment is one of the major things to take away from this thread, 40+ years of age and you're saying you're happy to spend in excess of £50,000 just to settle on a low paid job flying a light twin for an Air Taxi company?
(Do such companies still exist? - i'd put a bet on a high number of P1 hours required...)
I'd question your decision making...I say again, you WILL want to work to live, not the other way round...anyone above 40 years of age starting out now is taking a huge risk...
