Try a google search..I typed in "grilling wood", and a lot of information came up. I hope this give you somewhere to start. Also in the back of one of the books (How To Grill), there is a website for Blue Moon Woods, their address is www.bluemoonwoods.com
They are located in Sopchoppy, Florida. Don't know if that is near you, or anything about them...So your kind of on your own on this one. If they can't help you, perhaps they would know of a source near you. Hope this info helps you.
