I can easily recommend both these sites.

http://www.justinguitar.com/

Justin is a free site, no memberships, logins etc.
Has more than 600 + videos, (again) free. On his Main page you call select what level you want, style etc.

I really enjoy the courses ($49.xx) each. Absolutely worth the price. The trainer (lessons) are very well laid out. When you download the Main app, you get to try out all the courses (7) available, all contained in a single module.

I've purchase the following courses.

(a) Absolute Fretboard Trainer
(b) Guitar and Bass Trainer
(c) 100 Chords Method and
(d) Guitar Scales Method.
