Realistic Zombie Apocalypse Road Signs

I have created a zombie apocalypse-themed film and need realistic 3D models of apocalyptic road signs. On a budget so can't afford to spend too much.

Requirements:
- Designs should depict a world changed by a zombie outbreak.
- Focus on creating warning signs (e.g., Bone Crusher Territory).
- Highly detailed and realistic models.
- Textures and materials should enhance the post-apocalyptic look.
- Needs to then work with After Effects for composting in a 3D tracked scene.

Ideal Skills and Experience:
- Proficiency in 3D modeling software (e.g., Blender, Maya, 3ds Max).
- Strong understanding of realistic texturing and environmental design.
- Experience in creating themed assets for films or games.
- Attention to detail and ability to follow specific design briefs.

Please provide a portfolio showcasing relevant work.
