If you have to do part time it's your only option. Remember though, VET is a rip off to begin with. Soar charges $270 dual for an absolute basic LSA burning 20L of MOGAS.
80k is a lot of money when you'd have to buy 206 time afterwards.
If you're working why not self fund as much as you can, get a bank loan when you need to and negotiate a good rate for upfront payment? Save yourself a good 30k
