The greatest resource I have found for youth ministry would be this website. I have used countless resources from them and will continue to do so in the future. It costs $20/month, but this is what you get for that investment:
$20 to spend in their online store(everything is completely downloadable).
Student Leadership Training Material
Volunteer Training Video
Mentoring Audio for you
Parent Newsletter Builder (pure gold to help your parents win)
Video for you to use in services
Mystery download (game, series, video, etc)
Group Texting Tool
This does cost each month, but there is nothing that I have found that offers as much to help you win.
