I don't know about consignment but Tammy has some that are new and some that are used. She probably would be able to make some for you, or may be able to direct you to somewhere else if she can't. It's definitely worth a try. I highly recommend Blue Earth!
They may have some for you to look at and some on consignment. I know they could accommodate you on the custom end. I mostly had repair work done and they did right by me.
