If I were you, I would just stay in SPF and study PT for a diploma and hopefully a degree. Can even get sponsored by SPF to take PT dip at local poly or degree at unisim eventually. You only have a higher nitec cert, don't dream so big please. Get a diploma/degree first. Then if you come out and flunk at sales, at least you still can find job. Anyways, if you have a diploma or degree, you can promote faster within SPF and get more pay...
