Compensation for speaking to team

[coachgrd]

There's a great idea in another thread from an official who played for a coach in HS who would bring in an official to speak with his team each year. To be truthful, I've thought about doing the very same thing before. I'd not expect anyone to do this out of the goodness of their heart so what should I do in exchange for the time spent with my team? Gift certificate to a dining establishment? case of beer? cash? What would you expect in a similar situation?

Thanks, and as always, be kind.
