Pricing for one on one vocal coaching?

Hi everyone, I was recommended a few years ago to do training with a patsy rodenburg vocal trainer. I even got recommended a name, but this person charges $350 AUD per session for 8 sessions. And I’ve already paid for the first one. But I genuinely think it’s too much/pushing it

Is it normal for one on one coaching to be this much or am I being scammed?

I found a vocal coach in my area that’s cheaper for 6 sessions. $285 per session.
