Streamline and BAC Express are the two Shed operators that offer type rating courses with the non-promise of a job afterwards, basically a gamble for people who feel lucky.
I think Streamline also operate F27s on the same basis.
Not a great route at the moment as the death of Gill last September caused a glut of Shed-rated pilots on the job market who may or may not have been rehired by now.
