If you're not worried about doing it for profit, and more about just trying to see if you can do it then you can raise them without live rotifers or live phyto. You can use Otohime A as a first food, then NHBBS after that. The trouble with using dead foods is that you will fight water quality and not many will make it through, but it can be done. All you need is a small tank (5 or 10 gallon), a small air pump and stone (and ball valve to control flow), some AmQuel, a SeaChem Ammonia Alert, and some Otohime A, B1, B2, and C1.
You don't need greenwater unless you're using rotifers.
Otohime comes from Reed Mariculture so any LFS that carries Reef Nutrition can order it for you. It isn't cheap though, and you can't just buy one small package.
Rotifers are easy to raise though. You can buy them from Reed's too. Rotifers are easily raised on dead phyto from Reeds as well (RotiGrow to raise them, and RotiGreen for greenwater).
