the free lessons are great and im sure youll find some that are just right for you.
the greatness of this site comes not just from its content but its community, there are players on this site from where you are now to professional guitar players. if you have questions/concerns or are stuck, if you ask some one can help. while a paid account gets you access to all the lessons the forums are open (execpt a few of them) if you need help.
just starting out like your are the best thing you can do is ask questions. you said your time is limited well half hour a day is all that it really takes to get going. no one is born musicly inclined or super talented, practice is the only way to go.
for nw just play around a little bit on your new guitar, maybe pick up some chords and have fun youll be jamming in no time flat.
and good luck
