Welcome to GT...
Some instructor here do recommend having a private insructor. They have a disadvantage of not being able to see what you are doing right or wrong.
In my case I have two problems that would have been caught in person. One, I tend to lose posture causing fatigue and a short practice. Secondly, I tend to roll my guitar to view finger placement which makes it hard to fret clean chords.
Check out your local Community College for group classes. This may be a less expensive choice and a chance socialize with your guitar peers.
There is also a chord finder at the top right corner of the site page..
Keep on Pickin'
