Search youtube or google there are tons of tutorials out there, save you money. remember practice, practice and practice thats how you learn and get better. Post your results online and listen to the feed back your given, after a while you will get to learn who is giving the best advice. Try more advanced forums as well, yeah they will beat you up a little but you will get stronger for it.
Try sketching as well, take a piece of paper and pencil then sketch an object. Learning how to SEE an object will help you more than you will realise. For some this comes naturally others need to work at it as it did with me. This was the single most important lesson I was given and at first I thought they where talking sh*t as well. Try it.
Just trying and learning from your own mistakes is a much better way of learning, in art there really are not that many short cuts.
