Reply to DJ Mixing Techniques

So I've been looking around on the web for really good information on all of the different mixing techniques and I can't really find anything good except for a youtube video telling me to go to college to learn about it... Here's the thing... This is a passion of mine and I love doing it but I don't have the money to go to New York and learn so are there any websites, books, youtube videos, anything so that I can teach myself all the modern mixing techniques and scratching techniques and what not?? For example using chained effects, harmonic mixing, how to do remixes on the fly, dropping on the one... basically all the techniques they talk about in this video

Just without the college... Any info will be greatly appreciated
