Ryan,
If you have managed to save $50k (ish) you are obviously committed to the cause. Have you considered doing your licence part-time so you can remain in your current profession? The extra year or so won't make that much of a difference in the real scheme of things - especially given the current job market - which I doubt will change much over the next few years. Nothing worse than sitting around flying schools waiting waiting f'ing waiting while you could be out earning.
The extra cash will buy you plenty more options when the time comes to pack up and go bush with fresh cpl in hand.
Wish I'd done it that way. Just my 2c
