i am doing a job for a guy who wants video tutorials of angry birds original and angry birds seasons. he has asked me to tell him a price quote as per how many US$ per video . he also tells me that $1/video is not feasible as it is a lot of videos. I want to know why anyone would want to buy the videos? (if he is using it for an app or a CD how much could i make if i cut a deal with him so that I get a share of the profits):$$::$$: and how much should i be charging him per video as a professional. i am new to this field and hence need your suggestions.
