I had one of my cake customers contact me today and ask if she baked round sugar cookies if I could decorate tops (3 colors) for a work Christmas party.  100 cookies.....

I have no idea what to charge, as I don't do cookies.  I charge $2 per decorated cupcake, so I'm wondering if $1 per cookie is reasonable if she is baking them?

What do the experts say? :)  TIA!

AI would charge by the hour. How many hours will it take you to decorate the cookies, including prep and cleanup?

I wouldn't take that order... but if your willing too I think it depends on the complexity of the design and what your decorating it with. 

My prices start at $0.75/inch.  So a 2" round cookie would start at $1.50/cookie, a 3" round cookie would start at $2.25/cookie.  The design could make the price go up depending on the complexity.
