hello M8,
The only way in as far as i found was to knock on doors, send lots of c/vs and make lots of phone calls,
I got a trainees job after a very long 3 months but it was hard going!
the company i am with are looking for more trainees,
BUT they have to be referd by somebody they know or a agent, one of my m8s is a supervisor so he put in a word for me.
Just keep trying is all i can recommend, if you keep trying you will make it!
best of luck!
