Why don't you look at this:
http://www.learnandmaster.com/guitar/
Very structured and very comprehensive. I looked at all the free web stuff (including Justin Guitar) and still decided it was better to pay and get this. I'm glad that I did.
And if confidence is an issue the forums there are very helpful.
It isn't cheap but they do have a very liberal return policy. It is at least 30 days and I think more.
Good luck!
