C'mon our lad would this not be better asked in the Biz Jet forum?
If you're looking at speculative TR's then perhaps a form of Citation might offer more opportunities. Personally though only a fool would buy a speculative Biz Jet rating in the hope of getting a job, there are far too many types you see. You could get a Hawker rating next week only to find a job advert for an XLS position the following week, rinse and repeat.
