OT - Anyone on here a piano tuner?

Anyone on here a piano tuner? Or know one? I was thinking of taking a
home study course to become a piano tuner. Not so much a full time
thing....but as a supplmental thing. Do a tuning here and
there....particualry when I am saving up for major quilty purchase
items like a stitch regulator for my HQ16 or PCQuilter. Maybe one day I
could do it as partial income and then quilt the rest of the
time...something like that....

Plus I think it is downright interesting. My "real" work is so ethereal
(software) this would be nice to do something hands on...

I was just wondering if anyone learned from a home study course and
what did they think...? Did they make a career out of it? Etc. I don't
imagine myself getting all crazy...but maybe a word of mouth business
kinda thing.
