Need Help finding a plugin

So I’m not quite sure how to word this. I’ve got a site that hosts videos i’ve hosted the videos outside of my wordpress theme. However what I would like is a plug in that Customers can use to browse videos and if possible pay for them. Then they would get an email with the link and password for the video. Not sure if this is even possible or if I should just stop looking now. Thank You.

PS: I was looking at something like the Shopp plug in but not for Physical stuff..
