If the plane you hires comes with a HF then that is an added bonus, but if it doesn't then I wouldn’t be too worried. From my experience flying in the outback even at 500feet there is usually at least one other plane monitoring centre who can relay a message if needed and most are listening on 121.5 if something really gets out of hand.
As for approaching employers i would be wearing neat casual, maybe a pair of jeans and neat shirt. I wouldn’t worry about a uniform (but that’s just me)
Ill put in another vote for a 182. There’s nothing better than knowing that you have heaps of fuel in the tanks when flying in the outback especially when its a pvt flight
