...hmm - v. similar plan to mine.
What you will have to remember is that you can never go back to Oxon.!!
At 1000 hours, you should start to be useful to employers so, if you can afford to self-fund up to UK JAA FI(R) and, initially work part-time as an instructor and part-time in software to build your sours, you should be OK. The job market could up and you'd be well-placed for any positions going.
