Children's Ministry Internships

We are looking to develop a children's ministry internship program and I am wondering who of you have implemented such a program.  I have a few questions:

• What kind of response do you get from colleges - local? out of state?
• What is the rate of return - are interns generally interested in future full-time employment with your organization?
• Do you feel this is a good avenue for finding future leaders for your church?

It seems to me that so many in children's ministry seem to be "seasoned" and for us to be innovative and prepared for the future, we need an influx of younger, hungrier people with new and edgier ideas.  What do you think?
