Hey Hoopers!

I am involved with a fabulous circus and we are doing some performances this summer in which I will need a large hoop. I want to construct one large enough for two people to hoop in it at once..aka tandem hooping. We REALLY do not want to order the tubing of a website because the smallest amount it's sold in is 50ft quantities for $100. We will only need about 20ft of it. We've done an extensive search of home improvement stores, i.e. Home Depot, Lowes...and cannot find it available. Does anybody have or know of where we could get something appropriate that's not gunna bust our wallets???

Thanks!
