Create embedded video player and gallery

Create embedded player that I can use on my website to upload videos and to view them online. I need an option where people pay for the video and then view it and rate the video. please describe what it takes to create an embedded player that can be used for playing videos on the site? I need to know that you understand the functionality where people can upload their videos and others will pay and view them. So I need the following: 1. teachers upload videos and set a price (admin managed) 2. students can pay and view videos using an embedded player on our site 3. students must rate the videos after they view 4. students must invite more people
