If you are willing to pay a bit, think its like 15 bucks a month if you pay monthly or like 10 bucks if you pay early I would check out
Online Guitar Lessons | JamPlay.com
They have thousands of lessons all recorded in HD, There is an instructor in their chat room daily doing web group lessons and answering questions.
It has progress reports for each lesson you can use to keep track, tons of instructors ranging in all styles of music.
They even have a Kids lesson section by one of the instructors last I looked (havent been on it in months as I havent touched my guitar in a long time).
I highly recommend them from personal experience. The lessons are all very high quality and filmed from multiple angles plus its nice to be able to actually talk to the instructors through chat or the forums.
