Might as well just post them here. I'll one day have my tutorial up too but for now here's a buncha links that I'll add to when I come by more tutorials. The quality for each tutorial is different but look at which on suits you the best and work with it. The point of tutorials is to give you a basic idea and then you should evolve from them.
