I would suggest posting on your local Free cycle and Craig's list for used plastic bins. It might take a little while, but you can usually get what you want.

I am havin problems finding pictures or references online as to what commercial facilities are using for bins? Can anyone help here? Thanks

$4 totes at walmart are about as cheap as you'll get, you could ask fast food restauraunts for their buckets.

"commercial" facilities don't use stackables they use large stationary bins usually made of wood {{gwi:1339130}} .... you won't develop much of a "business" with small containers that can be moved around by hand in a basement considering the volume of inputs necessary and the time involved in hand sorting for saleable worms and/or castings, not to mention the time and difficulty involved in monitoring a large number of small containers for the management of ideal conditions .... most productive commercial operations will involve a flow system where the worms follow the inputs [down to up or side to side], and/or harvesting is machine aided

On a small scale I've used coca-cola tote trays (those red rectangular trays used for hauling coke from truck to store).
I worked at an office building where they had a small snack shop and the proprietor had no room to store the trays so he would throw them into the dumpster on a daily basis and I would fish them out on a daily basis and after a year I had about 100 of them, on a small scale they worked just fine for raising worms as a "thing to do" but if I were to raise worms as a "business" using this system, I would starve to death.
Now, on a large scale, in a Maryland climate, I have raised worms in my large compost piles over the winter, where the heat of the pile kept the worms warm, but when summer time temps hit, the worms split, this is why commercial worm farms have large shallow bins that are shielded from sunlight. the mass of a large pile gets too hot and sunlight is toxic to the worms.

thank everyoe for your help...Now I need to research the suggeted setups...

Check out the recent discussion 'my flow through bins.' I'm guessing you could find old garbage cans. I know the my city provides large wheeled trash cans that work with their trucks and replace them when they break. I don't know if these would be big enough for a business, but they might be free and need only some duct tape to make them usable for you, as well as the modifications to make them flow through bins.
