This is a pretty difficult choice, and I sympathise for you (I am rather older & more expereinced, but currently work away from home during the week, and will continue to do so next year). I am not an expert in the details of the current 'first year' rules for NQTs to gain QTS, but I seem to recall doing supply is not recommended. If that is the case then - if you can - working away from home for a year to gain QTS might be a good move, and then looking for a post nearer home. However if you can't find duch a post, then look at local supply? Good luck in either case.
