Surely you will continue applying for positions teaching either one of the subjects or all three. Many schools are now delivering business at KS3 often within the ICT timetable, which you could offer. Your main aim is to gain a teaching position, therefore apply for any vacancy, even if it is pure ICT. Waiting for the perfect Biz position may take much longer. Once you have taken up the post you will most probably end up delivering some biz/econ during your subsequent years at the school, especially if the school offers enterprise as you could become involved in that and therefore able to demonstrate your knowledge. I am a Biz/Econ graduate with a PGCE in Biz and ICT. My very first teaching post was KS4/KS5 Business. After a couple of years I took a job teaching ICT KS3-KS5. Then a successful application some years ago as Head of Biz KS4/KS5 included a couple of Y7 ICT classes each week. When the Head of ICT took a position elsewhere, I was asked to take on the teaching of KS4 ICT. I am now head of Biz/ICT and its great. My passion is in biz, as well as KS4/KS5 biz, I now deliver the ICT curriculum at KS3 within basic business concepts eg: ownership, marketing mix, recruitment, methods of production. It's far more fun that just ICT. Good luck with your interviews, just go with the flow and see what happens in your first post, and take it from there.
