-Low Voltage License Holder-

Cable companies usually price this per "drop" (ie cable). They generally don't break it out into man-hours.

With materials and labor in a drop ceiling, in relaxed jurisdictions, it's about $150 per "drop". This is also considering there are several "drops" being installed at once. If a single drop is ordered, it is going to cost alot more for a guy to show up in his van, walk it over with the local contact, unload his stuff, make two trips up the service elevator, do the work, clean up the ceiling dust, wait 20 minutes for the local contact to sign his work order, then pack up and leave. That single drop is going to be more like $700.

Back to jurisdictions, some places like Chicago require conduit, even for low voltage. Other considerations are whether or not the work must take place after-hours. There is usually a higher rate for this.
