first thing he will need is plenty of hives to steal frames and bees from to make up nuc's, the rest is all the equipment needed like nuc's, frames and foundation, the what way he will use to raise the queens like grafting, jenter or nicot, sugar for syrup, it can add up depending on the size of operation (number of queens wanting to raise), the big thing is bee's, takes a lot of bee's to raise a good number of queens, just imagine he grafts 30 cells to start with and gets lucky and hits 50%, now he has to have the 15 nuc's and if they are 5 framers like I use them he will at lest need 3 frames of bee's for each nuc and this will be needed at the same time, a frame of eggs or larva, frame caped brood and a frame of honey with 2 frames foundation or drawn frames (one of each) I rather foundation it give bee's something to work
