I have been making cakes for my children for the last couple of years. A local bakery had seen some of my work and asked if I would be willing to work on a contract basis to decorate cakes for them. The owner would make the cakes and then provide all the ingredients necessary to decorate. Therefore, I only need to charge for my labor.
In my research, I only see help with deciding how much to charge for a whole cake - no information on just how to price for my work. Please feel free to take a look at the pictures. So far, the cakes are a combination of sculpted as well as simply frosted.
I thought it would be very sporadic, however I have been given 3 orders already in a week to work on. So I need to come up with a way to calculate this fast!
If ingredients are already provided, I'd say $20-30/hour depending on your skill level and the cost of living in your area.
Be sure you have a contract signed by both parties before you start doing work.
I say aim high and see what transpires.
When I subcontracted my wedding cake only services for another business, they paid for 100% of everything and the base price that was paid was split 50/50 with additional charge options being paid directly to me, plus they also had to deliver everything.
