Sorry :/ ill look into other sites for you and we'll see what turns up. But like the previous poster said, ebay and amazon are great places to look. And remember to always be careful on the computer.
You could also build your own. There is plenty of great information out there about DIY book binding. Some folks take a simple path at first, and eventually move to much more complicated methods.
There are a number of options on Amazon you might want to look at. You can find them at http://www.amazon.com/s/?ie=UTF8&keywords=blank+grimoire&tag=googhydr-20&index=aps&hvadid=28618157007&hvpos=1t1&hvexid=&hvnetw=g&hvrand=6876141037610240998&hvpone=&hvptwo=&hvqmt=b&hvdev=c&ref=pd_sl_594jm31eg_b
