OK, so let me give an uneducated and totally inappropriate estimation here.
How much you need: enough to get them all wasted.
If Cate Blanchett (and probably a whole string of other beauties) attend, you need to make sure there is plenty. You are probably the one that needs to stay sober… so imagine, you walking around dozens of supermodels and hot actresses that have had too much to drink. Go for it man
And I hear you say “these people don’t drink”. Com’on you are the sales guy, make them drink!
