So, a coworker commissioned me to make a couple of cakes for some other coworkers (both of whom are also friends of mine). I charged him $40 for both, because I was really just charging for supplies. He then said “Hey, seriously, next time we do this, charge me more.” I do this as a hobby, not a business, so I have no concept of what a fair price would be. But now I have other people from their department asking about commissions… what do?
