ARM,I used to grow alfalfa sprouts. All I used was a large jar with a piece of nylon stocking rubber-banded around the top. As I recall you rinse them daily, and keep them in a cupboard/dark place. They grow easily and are very tasty.
I'd question seeds meant for planting, as they may be coated with something.
Have you tried a health food store or co-op?
