To me this seems like a perfect volunteer opportunity. Surely there are many people in TV who know sign language and who would be happy to place themselves on call for activities that require an interpreter, such as meetings, plays, classes and so forth. When a hearing-impaired person wishes to participate they could let this volunteer list know that they need an interpreter for a specific event. The volunteers could be coordinated by the Recreation Department, the Lifelong Learning College, or some other existing organization.

This approach would be much more in the spirit of TV than demanding paid interpreters at every event.
