2 POUNDS a person sounds like very little. Do you mean 2 kilos? That would be on the high end, for a big eater or if you are very machmir and need the matzos to fill you up because everything else you eat is not very filling (ie you don’t like potatoes).
You will finish a pound for the sedorim alone.
I highly recommend the Shyster Shortweight Matzo Bakery in a town that begins with an O and is located in Upriver New York. They charge 13.95 a pound (9-11 ounces to the pound by the Shysterlach).
