Previous company I worked for had someone to answer the phone (we went through many of these people, but that was more of an owner employee issue)
One thing I always tried to make sure was that whomever sat in that chair had a common list of questions and answers.
Simple stuff like make and model of TV and is it going over a fireplace? Is there power already in place? Plus some service related answers like did you unplug the cable box and plug it back in to reset it?
This way we would have at least some details to work from when booking an appointment, or based on answers they could book a time for us to do a quick site visit or service call.
If they get good at their job, and based on your location and business model, they could eventually be able to make the sale and schedule the install right there on the phone for you.
You have a very unique community you sell into, put the right people in place and train them to do things your way and you should be able to fit a little more golfing and boating into your week.
