Get yourselves together and start a balloon on-line shop, then you'll have access to all the balloons you can get your hands on. That's what BalloonAce did in the UK.
I might ask qualatex Australia for a business account and see how it goes. See what prices they'll give me.
I think they'll see thru your ruse: "Hey I think this guy is trying spend 1000's of dollars with us just to get tons of balloons 'on the cheap' for his pervy hobby. " Account Request Denied"
