Single pilot IFR air taxi flying really is some of the most demanding flying I can think of from a pure "you need experience to make decisions under pressure" point of view.
Few operators will look at you without 1000hrs TT, some (i.e. 200) multi hours and some IF hours.
Rightly so. I wouldn't like to be by myself on a dark and gusty night in a performace limited twin battling icing making an approach to minimums on an NDB to a smallish runway with limited fire cover. An everday occurance to many UK air taki pilots.
The flying instruction path is the more sensibly trodden.
