Have you googled, or looked on youtube? There are a bunch of very respectable ones, and usually the proof will be in how good their final material looks, etc, which makes sorting through the chaff not too difficult.
Do you have a particular style of wood you're looking to replicate? You also got some good feedback in a previous thread about how to analyze and approach a complex wood material, which could help you adapt a more generic wood tutorial to suit your needs.
