Obviously no expert, no experience.
I dug up 1 worm from the soil near foundation of house, took a trowelful of soil,
put them into a clean yoghurt container, punched airholes in lid.
Tiny bit of mist/water inside, added a few potato peelings, placed in a warm dark basement.
Dean, you said you bought night crawlers.
I'd find a clean plastic "box" like those dark-blue organizers made by Rubbermaid with a lid that fits.
Shred up some newspaper (for bedding), place in one corner, then native soil, rotten damp leaves in the other corner.
A few veg peelings from kitchen, banana peels (cut up), and toss worms in.
I think that's how it's done.

Anybody else?
Barb
ps...peelings, etc. should be damp, never flooded wet.
