http://www.flintknappers.com/. Look up Steve Holloway a.k.a.
bohunter on Youtube. Just type in
bohunter without the "w" after "bow", and you will find him. Also, Craig Ratzat, Mark Bracken at flintknappingtools.com, and Randy Beach all have good advice.
Be careful, when I started out awhile back, I spent a lot of money on new tools. It's really easy to get caught up in it. Mark Bracken has the best, in my opinion, DVD available by himself on his website. Another must is the book "The Art of Flintknapping" by DC Waldorf. It covers all of the basic fundamentals of flintknapping, and even how to find natural resources for flint/chert. All in all, the most expensive material in flintknapping is the flint/chert itself. I live in Kentucky where the most prominent types of chert are Sonora, Carter Cave, Kentucky Hornstone, and Ft Payne. Even in living in the native state of these natural raw materials you wouldn't believe how hard it is to find them in their natural state. I have around 4 tons of Ft Payne since I can get it at a local quarry for $8 a ton, but have to pay close to $5 / lb. for all of the others due to their scarcity. Then again, Sonora and Carter Cave are as scarce as hens teeth, and I would have to pay as much as $10 a pound for it in rough spalls. The best thing to learn at first is how to spall a rock, and knock off a workable piece of chert.
As for 'cooking' or heat treating chert .....
Heat treating makes a lot of materials more workable, and even more appealing to the eye. Although, there are a lot of risks in doing this, so anyone who does it should do it right, and not just in your oven at home. Some cherts need or are improved by heating while other don't need it at all and are not affected by it. Sonora, Ft Payne (black) and KY Hornstone do not need treating, but Ft. Payne (tan), Flint Ridge, Burlington Chert, Buffalo River and almost all Texas types are drastically improved by heat. The only chert or material that I am aware of that REQUIRES heat treating is Coral from around the Gulf / Florida Panhandle area, but I've never worked it so I don't know anything about it.
