CTC Aviation
Instructing is arguably the better route to take. You are going to gather so much more knowledge and experience this way than temping or pursuing a non flying stop gap role. Unfortunately since September an awful lot of CPL/IR graduates have gained FIC ratings and the job market for instructors is perhaps as lean as it is for airline work.
Maybe the ideal solution is to instruct at weekends - always more requirement than weekdays - and work Monday to Friday in a job that is more likely to pay off your debts.
For what it's worth, I went down the instructor route and, if I had my time again, would do the same.
Good Luck!
