How much Alcohol would i need for a college party ?

Im having a huge party and the theme is kind of CandyLand meets pink playboy mansion
and I dont know how much alcohol I would actually need to provide.
Like the names and the approx. cost of it all ?

i throw those all the time but i get the most exotic beers and liquor

i get spaten optimator - which is about 20.00 a case (beer)
bacardi 151
goldschlager peppermint schnapps
jagermeister
smirnoff vodka
cranberry juice
fat tire (beer)
johnny walker
jim bean
jack daniels
ameretto almond liquor
dekuyper
southern comfort peach liquor

you can make a lot of drinks with those

mix 151, goldschlager and jagermeister and shake it and pour it into a shot (Liquid Cocaine)
Mix Smirnoff Vodka and Cranberry Juice (a chill drink)
Johnny Walker, Jim Bean, and Jack Daniels (Three Wise Men)

the next is harder.
take a margarita glass or any glass
then pout 1/2 oz of 151 rum, light it up
while lit, pour the 1/2 oz of ameretto and 1/2 dekuyper and 1/2 southern comfort one by one
then blow off the fire...and shoot it...pour it all on your mouth and have fun having sex with 3 people when in reality you only having sex with 1
