A little bit of info for you. Getting 24awg stranded PE insulated OCC silver manufactured costs about $10 per meter if you buy a large amount, ballpark figure. By large amount, I mean about 2000-3000 meters. So about 20-30 grand. Occasionally you can find a place that will make only 500 meters of it but this is rare. This is why there aren't a huge number of cable outfits on headfi that have such a wire, it isn't an off the rack product. The wire in the cable is worth maybe $50-100, but the sheer amount you have to buy at a time is on part with a nice new car, price wise. So likely you are going to come up with nothing - your best bet if you want this is to get a Moon Silver Dragon, a TWAg V2, or a Toxic Cables Silver Poison.
Edit: The only way you will get a small amount is if you convince a company to make you a sample. Essentially they need to think that the cost to them to start up the production line is worth it, that you're a serious potential client. Most will not do this, but with the right connections it can be done. Then you are looking at $1000-2000 depending on gauge and other factors for a 100 meter roll of it.
