Is there anyone who knows how I can get in touch with the manufacturer of Hill-Berg Fabrics?

I'd like to buy a large amount of fabrics from Hill-Berg. Is there anyone out there who knows who manufactures this line? What country is the company based in? Anyone with contact numbers? I know Fabricland in Bristol, UK sell them, but I need them cheaper so would like to buy direct from the manufacturer. Is there anyone who knows anything about this? Thank you for reading this.
