Immersive Virtual Collection exhibit with CDN integration

Looking for a freelance developer to develop a professional, virtual collection exhibit (3D) with integration of video content to Content Delivery Networks. This needs to be a highly scalable solution, as thousands of potential viewers and users are anticipated. As a starting point, this website needs to house a certain number of items, where new items can be added weekly. In addition, as each item is clicked on by individuals visiting the exhibit, there needs to be a pop-up of either text or video content which then describes each item, which will be provided by the subject matter expert on the collection. Further details can be discussed with interested parties.
