I am going to do it all in butter cream

It says it serves 44 people. So at $2 (low end) a slice your at $88. It's now overly detailed so I think $80-$90 is fair (of course depending on your area).

Good Luck & Post pictures when your done

thank you for the quick response! I wont be making it until June 14th just wanted to get an idea on if I was on track when I quoted her 85.00 for the cake!
