Depends on how much the intern would be getting out of the experience besides pay. If you're actually teaching/mentoring them, then you don't necessarily need to pay them anything. If you don't have marketing/sales expertise yourselves and therefore "intern" is just a way of saying you don't want to be bound by traditional employment practices, then that's something different altogether, and you're probably not going about this the right way. Why the term "intern"?
