Realistic Horror / Open World Woods Horror Movie Animator

Independent filmmaker hiring an animator to create a realistic world and horror elements such as gore, terror, horror, etc. We can record the actors as well and the woods and abandoned building at the end of the film, for reference, etc. We are looking to see what it would cost for a 45-minute version, a 60-minute version, and a 80-minute version. The more realistic the better. Think atmosphere of a dark and moody foggy woods type of video game/animation.
