Here is the best source for aftermarket wooden stocks:

I've bought a set and they are high quality.
I thought highly of IWD work as well. But I didn't get anything from them when a well respected founding mod of VEPR.org WENT OFFF!!!! on Iron Wood and how, I will put it delicately, how "disappointed" he has found many other people to be with the end result. I was Shocked at his vehemence.
I am glad that you have found their work to be top quality. If you don't mind my inquiry, what style and finish did you get from them? Any pics?
I have found that the Canadian accessory stores are only prohibited from selling guns & ammo (and perhaps bbl's & receivers, I do not know), everything else I've gotten there has been actually much cheaper. The same is true of many UK & E. European Co.s. We (in the U.S.) do not have to pay the Value Added Tax, which is not insignificant. However, I have pulled out of deals because they will want to stay with a bank transfer only, and I am reluctant to do any large overseas purchase without the protection of a credit card. I lost a Dragunov because of that three months ago. That's just my personal preference, however.
