I agree with Ankit. I'm not sure how people are getting to their cost per user recommendations, but no reasonable marketer is going to pay you for that. Everything needs to be charged per thousand views as that's the industry standard (CPM or "Cost per Mille" which means "Cost per Thousand"). Video CPMs range anywhere from $5-$40 and I'd say the typically sweet spot that brands/agencies are used to paying would be $10-$25. At 10k views a day, you can reasonably make $100-$250 a day if you fill all your available inventory.
