think about the C525
I know a guy in the same position who self funded a type rating on the c525.
he is now working for centreline out of eggd where he is paid well gaining jet time and will be very employable for heavier equipment in a year or so.
the type rating is available in germany at around £8k
the c525 is a good starting point as there are many varients included in the same tr, and lots of european operators.
centreline have a second cj to crew and are looking for more fo,s
