film & serie app

Hello I am looking for a professional in the creation of mobile application and website.Here are the details of the application I want: I want an application where we can watch movies, series, videos, and music. In fact it is a mix of Netflix, Youtube and Spotify. The goal is that in the application there is a registration for seller account (those who put their video, film, series or music in the application to sell it at the price they want), and a registration for buyer account (those who pay to view).That's just the goal but I have specific requirements that I want for my application when we will agree for the budget, I take you it's a bit complex but if you think you can make a modern application with no bug and performance I award it to you.
