So I was asked to make a firetruck grooms cake for 130 servings! First of all I've never done a sculpted cake this big before so I wouldn't even know where to start and second of all how much cake would I need to make a cake this large?? And lastly... how much do I charge for something like this?? Thanks in advance for your advice

So wow, what a big cake. Should be lots of fun even if you haven't done this before. I hope you post pictures and charge what you're worth - at least a few hundred bucks, Maybe even more. (Are you making the wedding cake, too?)

You start by figuring out how much cake needed to *start* your carving and charge for every serving in that much cake.  As an example say you use  two 12x16 sheets and a 9x12.  That about 135 servings.  Yes, you will cut away some of that but you still charge for that much.

Make sure you have a *very* solid base board.  That much cake is going to be very heary.

You may want to make a store front w/firetruck in fromt of it instead of all in the firetruck.  Don't know if customer will go for that idea but you can ask.

AWhat is the customer's budget? Depending on the complexity you are probably looking at something in the $600-1000 range.
