For BAKERS ONLY, Could you help me?

Yes you can freeze it. You didn't say if you were going to frost it or not, but if you are going to frost it, I would NOT freeze the cake with the frosting. You should "crumb coat" the cake, wrap in Saran Wrap or however you were going to store it in the freezer, something airtight would be best, then on Sunday, finish the icing of the cake, and it will be really easy to frost because the cake will be really cold!
