There's tons of video tutorials on YouTube, but you probably won't find much on modeling in general. If you can pick an object you want to model and search for a tutorial for that (for instance, modeling a car is pretty popular), it will be much easier to find a tutorial. Outside of that, your best bet for a tutorial that covers modeling in general will be a basics tutorial, which won't be useful for anyone who already knows the basics.
Other than that, you could always buy a book. If you're willing to shell out a few bucks, that would be your best bet on learning modeling in general. I should have a list of books covering modeling that I could post if you are interested in that.
