One of the best things about the internet is the access to FREE KNOWLEDGE! So much guitar stuff out there! There are thousands of guys out there with "free" lessons...usually to try and get you to buy something...but aside from a little "commercial" in the lesson there is a lot of value to be had...

Youtube has so many but my favorite there are Marty and his protégé "Papastash"
