ISF is a training and certification program- as far as I know, no one who attends the training and is qualified is required to do anything specific. The ISF doesnt really offer the service- anyone can calibrate a TV in theory- the ISF just offers a certification program for people (similar, I would say, to computer certifications).
There is a company in my neck of the woods that has a similar situation- their ISF guy is not available for Hire-- instead he only works on calibration and maintaining installed systems for this one company. I don't imagine ISF could require him to work for hire-- he's simply contracted to do service for a specific company.
In my opinion a better car analogy would be a mechanic hired and trained specifically to maintain a fleet of vehicles sold by a specific dealership... The dealership spent the money on his training specifically to offer an added value to their customers. Or, again- computer certification--- just because Bob at Networking Assistance Inc has 4 microsoft certifications,and he's listed on their site as certified-- he's not obligated to work on your computer, and is more than in his rights to only offer his knowledge and training to customers who purchase equipment direct from his company...
I would suggest scheduling a service from one of the half-dozen TOURING calibrators (like the HTF's own Gregg Loewen or MichaelTLV)--- you might read the archived thread on ISF calibration, if you're interested in potential "problems":
(nevermind, guess this thread was deleted from the archive)
