The Hawker 1000 job sounds like Segrave, since there are not many Hawker 1000's out there. If so, the QOL will not be all that great, if that is what you are looking for. If you like to travel a lot, the 135 job sounds best, but if you just want the money, then the PC12 job may be best.
My son flew for an airline for 6 years, then he thought he wanted a better QOL and quit for a 91 gig flying a Cessna Citation, and was home every day with week-ends and holidays off, but the pay was capped after 2 years. The other problem was the flights that he had, 250 miles running a shuttle----boring job, no travel, a lot of sitting around---but home every night. He quit that job and went back to the airlines, and has no regrets, since he flies with SWA now.
So you have to ask yourself what is more important, money, QOL, or flying all over the country 16 days a month. The other thing too think about is, what direction do you want to go in your career, if it is airlines, forget about the 91 gig, and pursue the airlines while working with the Hawker job.
Hope my input helps, but no one can make the final decision except YOU.
GOOD LUCK!!!
