I'd go with the suggestions above. HOWEVER, we can't really tell you because we don't know how heavy-handed you will be with the amount of icing for each cupcake. Also, if you use a "whipped" (contains air) frosting, it will go further than thick, creamy icing.
I suggest you read this thread asking "How much icing for 400 cupcakes?"
It will provide a LOT of information and give you an excellent idea of how much to order along with the two suggestions above.
