CONVEYOR BELT ROLLERS

Making a small demo for the conical rollers for conveyor belt systems. The attached clip would give an idea about the actual product to be created and the possible camera angles etc. The material is possibly steel which is painted, and the rollers are some kinda rubber material. Over all duration of animation would possibly 20 – 30 seconds, but not sure at the moment – so maybe we could get an estimate for cost per second or some such??
I would appreciate a costing for this in INR .
Thanks,
