I have only brought them a couple of rugs. Nothing too fancy, just some larger wools that I didn't want to fook with that needed a good flush. The came out clean and were nicely "gift wrapped" for delivery.
They run the machine usually at least twice a week when the get enough to run a "batch".
They have a nice wholesale price list so you can get a rough idea what they are going to charge you, and you can charge the customer accordingly.
They will also pick up directly from the customer if needed for a small fee, and will even charge the customer on your letterhead receipts and cut you the difference.
What you should do is take a ride over there and check out the plant. It's really cool to see everything first hand.
Have them put you in their system, and get a price list.
If I get a chance to scan mine I can send it to you if you don't want to run by there, but you really should. you'll get a kick out of it.
