Server side rendering on the web

Hi! Does anybody know a server which I can upload my blender scene into and than request a rendered image? I mean I would like to send to this server my scene id, camera position and direction and than recieve a rendered image. All this should happen automatically in real-time using some web interface API. Request is generated from my three,js script in users browser and resulting image should be loaded to users browser.

I know about but it is too expensive and hard to try.
