I believe that BAS require a reasonable amount of previous multi engine experience.
Interesting flying jobs:
FR Aviation: Target towing and low level threat simulation in Falcon Bizjets on subcontract for the RAF and RN. Captains are nearly all ex military, but most of the Co-pilots are civilian, 1000 hours needed to apply alot of instructors employed there in the past.
Bush flying in Africa for companies like Zimex aviation.
There are always the occasional flying job in hostile locations: ie: have seen King Air jobs in Afganistan advertised before now. However significant hours and previous King Air needed to apply for this one.
Afraid JB, night freight does not involve lots of flying, typically 300 hours per year at most night freight ops on average. Again most night freight operators require about a 1000 hours for new FOs to ensure that the ATPL can be unfrozen in a couple years.
Bush flying in Africa you can get a job on a 206 with just the bare minimum 250 hours CPL and when you gain experience it is possible to move onto the Caravan and Kingair.
