There are website were you can order a Russian queen but its harder to introduce her to different types of bees and longer. (takes about a month to introduce her into like Italian hive, best to buy Russian queen already with bees in package, if you just get the queen you will have to split your hive into two sections, bottom with Italian queen and old bees and top deep hive with new bees and keep her in cage for about a week and go on from there, after a month you can kill the Italian queen or create a nuc, then you can introduce the rest of bees. )
It might be good to check with Bob and see if he'll have any Russian queens available during the conference. It's his yard that will be on tour. Otherwise, he can probably ship after things all the beeks leave town and settle down a bit.
