Recruiting Interns

I'd like recruit some interns to assist within my business.
The majority of interns I am aware of are motivated to join because its something to add to their resume.
I'd like to hear from some of the experienced searchers on this topic.

How how did you get in contact with these interns?
Upon what terms did you agree to grow both them and your organization?
And What was the best way you found to effectively utilize these individuals?
