I'd advise you to get proper lessons. If your serious about something then anything free won't get you very far.
I teach music for a living, and I disagree with this statement.
I would advise you to check it out online, see what you can do with it, and if it's something you enjoy, THEN get a private teacher. It often surprises people how much work there actually is in playing an instrument.
I tend to teach woodwinds and piano, so I see that attitude of 'aw, it'll be easy' all too often. It's a pain for the teacher too, because if you don't practice, and you don't work at it, they will be annoyed.
So to save you money, and to save the teacher sanity, I would suggest checking online first, and then I suggest you get a good teacher. not someone who's only been doing it for a month, but people who have a decent grounding. you're lucky, because guitar is probably the most common instrument in the world, and so there are tons of teachers. your local music store probably runs lessons.
