I feel your pain. I remember being an unemployed NQT and being helpfully given advice on how I could attend a course to "transfer my skills" (I tried explaining that as teacher training had been a career change I was already transferring some skills!). And, another one on how to complete and application form or write a CV - my previous employment had been in recruitment/HR where I had trained others to do this. Very frustrating - as is the painful having to sign off every time you manage to get supply over the 2 hours or something you're allowed to do. Keep calm, keep trying and, if you can consider moving to another part of the country where there might be more jobs. That's what I ended up doing.
