Bait worms

Hello everyone

I am not a fisherman - or angler, whichever you prefer - but I have an
enterprise which could be of interest to your sport. I breed worms for
producing compost from waste produce and manure. These worms are of the
redworm type - which I believe you call brandlings. My question is this: how
could I market the large quantity of surplus worms that I produce? How do
anglers normally buy their bait worms, in what quantity, how are they
normally collected and what is the normal price? I am thinking of some sort
of mail order or delivery enterprise, so I wonder if you chaps could tell me
if there is any demand for this sort of thing.

Regards.

Giles
