With the surge in demand for lessons of all kinds at Guitar Center, my boss says we're short on singing instructors. The one other piano teacher at my store is a combination singing and piano teacher but teaches one or the other. I prefer to teach piano WITH vocal if I do vocal-- which I haven't done until perhaps soon-- given the situation. So it's fairly easy for me to transition if I make the attempt I think-- as long as the student agrees to learn basic keyboard/piano skills, I can transfer some vocal skills. In pursuit of that, I'll now create a video playlist of vocal lesson videos I find interesting. I can pretty much guarantee that there won't be anyone teaching BOTH piano/keys and voice as a matter of course. In my opinion, you can't have one without the other. Similarly, the person wanting to sing should pick up a guitar or ukelele at least... something!! You simply cannot expect to sing if you don't have an instrument, in my view.
