You're not, OP....

also, feels pretty obvious you haven't been involved in bidding jobs before - these initial numbers set expectations. If "dad" valued the kid's talent and time, he would have said, "they'll give you a number" and/or the message to kid would not have been closed, it would have been open. So instead of, "you'll do this, thanks bye" it would be a question to kid prior saying, "I know a lot goes into your work, is $500 a good ballpark to give my friend for something like this?"

It's about expectations and entitlement - you're essentially my property, so I decided it would be this is indicative of a problem with "dad's" approach.
