There is no shortage of zero muticrew time FO's and there are more than enough willing to pay for type ratings if you haven't enough cold applications a couple of days open application on the internet will get you a couple hundred applicants for a job.
Captains completely different story..... 1000 hours plus PIC on a JAR25 machine and agency's are pestering you. A lot of airlines will give you a nice bonus if you introduce someone that's experienced and qualified (with or without type rating) for a DEC position.
