I had some success with very few manufactures. I am actually trying to start a sock company myself! I have preliminary designs that many people like but I can't find a manufacturer that seems to work with me on fabrics and is responsive. I did get some prototypes made from a few and I can put you in touch with them. There is a list of manufacturers at http://www.legsource.com/Mill_website_links.htm. However, I probably contacted 20 manufactures in the US and in 8 other countries with very disappointing results. I also contacted the North Carolina Hosiery Technology outfit and they were also unresponsive. Please let me know if you find some and also if you want to try to join forces on this.
