Hi! I am a hobby baker/decorator but was recently asked to do a big cake job for my brothers boss.
For a very large (75 adults, 50 kids) birthday party for 1 year old twin girls:
2 3d ladybug cakes (I used the wilton soccer ball for the body and the mini ball pan for the head on top of a 12" base (2 layers) - covered in fondant
12 cupcakes with buttercream frosting (each with a leaf, flower and mini ladybug on top)
2 smash cakes
I only had a week notice and had to buy my supplies local so couldn't get any real discounts.
I was promised reimbursement of my materials cost (ended up being about $250) + whatever I wanted for my labor.
I spent a week on this - about 35-40 hrs on it.
What do you think is fair? FYI I live in NYC.
