So after I started getting serious into playing guitar, I have been really wanting to learn to sing. I live in Washington, and it's a bit hard to find vocal teachers (or know which ones are good), but one I talked to was asking $1 / minute for 30 or 60 minutes. It seems a bit pricey to me, but maybe not?

I guess while I'm at it, does anyone know what guitar lessons generally cost? I used to take them for $35/45 min, but I've only ever had one guitar teacher.
I study music in university and some of the instructors charge between 50-100 an hour for private lesson. They're professionals though, I would suggest not going past 40 for an hour.
