In case any other members would benefit, I work with contractors who buy bulk assemblies (cables and wires) from a business called Beach Wire and Cable, in Huntington Beach (California).
However, Beach Wire and Cable also will deal directly with the public, so I was able to buy a 50-foot HDMI cable (already assembled) for $38.00 (available for pickup immediately; no waiting).
One of the contractors with whom I work told me the cable I bought does not have a "brand name", but is otherwise just as good as any "brand name" cable.
So, I was able to connect my computer to my TV, without having to relocate either device.
