Most tutorials tend to be modeller specific, and if you don't have a 3D modeller already that will be your first big decision. You can get somewhere with a free modeller (I know I have), but it will probably be more work. My tutorial will give you some idea of the processes involved. At least you can decide whether you still want to try it. :)
