Youth Survey Incentives

Hey folks! I’m working on a survey for young people regarding content services to help them with their development, and am trying to figure out an incentive that will lead to the most insightful answers. We want to make it open enough that a monetary incentive for every answer isn’t feasible. We were considering a random drawing for gift eCards entering all who answer, but also are thinking that maybe we pick 3 answers to award the incentive to (kind of like “best essay”). I’m not sure of the legality of those options (this is in Illinois) - anyone have info on that?
