I'm designing a logo for an event put on by a non-profit, and I am giving them a really good deal on it as they cannot afford what it is worth. It is a cause I believe in so I would like to help them succeed.
That being said, if they decide to sell merchandise with the logo, would it be inappropriate to expect a portion?
I am thinking of granting rights to all printed and online media, but merchandising rights would be a separate licensing fee (is this how I would word it?).
Would this be alright to put in a contract? I know most logos sign over all-rights, but the client would also pay more for this clause.
Edit: the non-profit is not a charity, and receives funding and grants. They also make quite a bit of money from this event and others, as well as member fees. I am privy to their available accounts and know they can afford to pay, but they don't understand the value of graphic design.
Also, if this question has been asked before, please send me a link. I looked and couldn't find one.
