I did my CPL and AFI course in 1991 to 1992 and did not get a full-time job till spring 1994 - only did about 130 hours in the first 18 months as a part-timer most of which I did not get paid for. After 18 months full-time instructing I went back to my previous profession and continued part-time instructing for the next four years. I went full-time again in 1999 and have been busy ever since.
Since then we had the 2001 slump after 11th Sept which coincided with all the heavy flooding in the south east - three months of awful weather - some schools went bust. But it always seems to turn around.
Here we are in the middle of the recession and I have never been so busy and booked up, as everyone wants to do instructor courses! As someone else has said, you have to be flexible in where you are prepared to go and then you will get a job as there are still plenty out there, but if you hold out for working down the road you may have a long wait.
