How much should I charge for a two layer cake feeding 75 people? 

whatever your base price is times 75 — i’d say that’s probably buttercream and $5 is reasonable — so is that $375?

but are doing the two tiers?

can you pipe the flowers and scrolls? 

also:

there is some kind of new member delay on being able to "reply" to posts so please start a new thread to continue any discussion -- at some point all of a sudden you will be enabled to "reply" but not for a while -- maybe like 30 days — I think it might have to do with time and activity levels -- please respond by starting a new thread if you want/need to —

best to you

It would take me 6 years to do the piping!
