I'd say your in luck then Sleek. I'm not a great source for where and what type of stone to get but novaculite seems to be pretty easy to find at all your normal Flint knapping supply stores online.
Personally my favorite place to get stone is from meets. I like to be able to see the stone, ask questions to the vendor or knapper and you can save a bundle on no shipping. Sometimes you can buy a small amount try it to see if you like it and get more if you do. I've learned to save my very limited play money for the Primitive Meets. Make a list of everything I need before I go and restock for another year.
