HI med flyer,
I cant say for sure your king air time is worth nothing as i dont know you but i have done the reconversion,having be1900 capt(single pilot)as well as SA227(metro3)as capt and no jobs for the last 6 months and oh yes i have a 737 rating..
Chose widely..king air is basically like a seneca..dont expect too much out of it..
I have all the info on converting licences and hiring in the uk.You are welcome to pm me for questions about it.
Regards,
