I am in a similar boat to you, i have over 1800 hours, 1100 Turbine and 160 Jet, both Mulit crew, and Airlines not interested either. I have gone back into Corporate which maybe a good idea for you.
Only Airline that was interested were Flybe, but i couldnt get any info out of them. Try BAC express, i think they want people and your close tocommand hours i think according to PPJN.
