Hi,
I specialize in 3D graphics and have a lot of experience in 3D and 2D technologies such as WebGL, HTML5, Unity 3D, [login to view URL], ...etc.
What could actually be very useful for your project is to create it in HTML5 WebGL which would produce an animation that you could interact with, i.e, rotate the container ....etc. You could then possibly use that in other ways for your site.
For this specific project we would record the animation for your landing page unless you'd like a container there that the user can also interact with. So possibly the user could rotate the container and select the doors, with writing such as "Enter" on them, they then open and the camera zooms in and you enter the site.
Have a look at my profile for images and details from other projects that I've worked on. I'm allocating time for new projects now, so let me know what you need and when you'd like to get started.
