What part of the world are you in? I teach guitar on the Derbys/Notts boarder. It can be difficult to find the right tutor and it is not a bad idea try a few until you find one that fits. The rgt is a respected specialist in guitar education and has a vast data base of registered tutors. Have a look here for a tutor in your area. https://www.rgt.org/tutors/index.php
One is only enough if you don't own a guitar. The most accurate figure for enough is one more than you already have.
Last summer I had 7 all from the 1970's Honda CB250, 400 and 750, Suzuki TS185 , GT250 and GS750 together with a 1200 Bandit. I've sold a few over the winter and I'm left with the CB250, TS185, GT250 and the Bandit
the second one, it was the first of the square ones which is why I never took to it as I like my bikes "round"
