We recently learned about how to price and gauge time, etc in my pastry classes.
I just briefly looking over that cake, with the size it'd need to be, and all the items, the least I'd charge for it is 20 dollars a slice. My quote would have been at least 6,000. Your bride better be thanking her lucky stars that you're a nice person!
Holy freaking cake! ha!
Of course, I also live in CT so things are higher priced here.
