Animation of my .stl files of Pump with inlet-outlet water in Blender

I am looking for a skilled animator who can create a realistic animation of my .stl files of a pump with inlet-outlet water in Blender. The animation should be more than 1 minute in duration and should include background music. I am looking for a realistic style for the animation. The ideal freelancer for this project should have experience with Blender and be able to create high-quality, detailed animations. They should also have experience working with .stl files and be able to create realistic water effects. If you have a portfolio of similar work, please include it in your proposal.
