I'm doing a vegan wedding cake for a young couple who are also having an after party later that evening with 100 guests. They are ordering a small version of the wedding cake to serve only 40 people for the after party and I will be doing a dessert buffet of minis. I am charging separate for the after party cake and $5.25/head for the minis. I will swing by, set it up, then leave. Since they wanted something different, I suggested a flambe station and they were very excited with the idea. I would stay for a set number of hours (not sure how long yet, any suggestions?) and refill the desserts on the buffet. I would have pre-chilled bowls of vegan ice cream and guests can order which fruit topping they would like and I flambe it in front of them. It would be served with vegan whipped topping and roasted chopped nuts. I would also clean up my own mess. They haven't picked their venue yet b/c they need to find the space to have live bands so it could be a club or a large restaurant. I will probably have to rent the plates, bowls, etc. and obviously clean and return those as well. I can figure out the cost for ingredients and rentals, but the part I am having trouble figuring out is how much to charge for the labor so I can work that into a per head cost. How do you price labor for a service like this?
