Jaap Flentri's aircraft are usually tied up on long term jobs with charter operators up north but occasionally come back down to Jandakot and may be available.
Wannabe QF, so you are suggesting that the hirer goes into ACFT's reception to pick up the keys and announces, "Oh I have done a deal with Mr PQY and I am hiring off him direct". Despite the fact that ACFT maintain the bookings, keep the thing clean, make sure it is serviceable (you know all those little things like oil, cleaning materials etc) and probably pay their staff in the process to do so.
