How to deploy a server with local storage of media content?

Question

Server equipment

1. There is a website in the cloud. Media content (video files) is hosted on the same host as the site.
2. There is an organization (far from Moscow). This organization has 150 users (with the prospect of growing to 250-300).
3. The organization has a rather narrow Internet channel, which will not allow users to view media content at the same time.
4. There is an idea of ​​local placement of content (on a server in an organization) and raising local servers (web, dns).
5. The user accesses the site, but when trying to view media content, the web server redirects the request to the local storage, i.e. all site content is displayed from the Internet, and media - from local storage.
Is it possible to organize such a scheme? How to maximize the degree of security (the server with the content will be located in the local network of a third-party organization, i.e. the administrator will have physical access)? What is the estimated cost of such a development?
