How much are you looking for?? I can give you a couple of cups if you want. Personally I don't think "live sand" is a big deal. All sand ends up live, real quick too, sure some sand out of an active tank will have some pods, and bacteria in there, but your "live rock" has the same. I have 2 bags of Tropic Edin substrate, 30lb bags, new in bag, that could be had for reasonable. Pm if interested.
