Journalistic Ethics-Possible conflict of interest- youth journalism program-Need Insight?

I work for an after school journalism program. We provide outlets for youth volunteers to work after school on professional news stories for print. We advertise ourselves as a professional news service. Recently one of our volunteers came up with a new story idea and while looking for proper interviewees one of my co-workers/managers suggested my team set up an interview with a service that could provide insight on the story. It has come to my attention that the service my manager suggested actually EMPLOYS her. For my own part, my team has no intention of coddling or advertising for this service. We just want information, insight and the rest. However, this might be a "conflict of interest, real or imagined" and it would be up to me to cancel the interview. I need a decisive answer soon.
