I think BJC and Anticables will both entertain this custom cable if you call them. It shouldn't be hard for them to accommodate.
If not, also look into the BL-1 Series II from DH Labs. You can call Greg directly from their website and he will be able to make them for you. Tell him Juan sent you.
In full disclosure am one of his dealers, but honestly that may be the best money spent on a cable in your price range.
