cooking tip substitution?

i just finished reading this cooking tip:

Making Better Pizza Crusts:

Use high-gluten flour such as Pillsbury Bread Flour and Gold Medal Better for Bread. Use 1 oz. dough portion or less per 1" pizza diameter (for example, 7 oz. dough = 8" pizza). Store individual raw dough portions dusted with flour in Ziploc bags in refrigerator up to a week or in freezer up to a month. Bake on pizza stone or pizza screen for crisper crust.

i’m wondering what to do for someone with celiac. suggestions?
