3D Modelling and Rendering

We are seeking a skilled 3D artist to create a realistic 3D model of a product and render it in a photorealistic style. The ideal freelancer should have experience with 3D modeling and rendering, and be able to deliver accurate, visually appealing results within the project timeline. The final product will be an animation that simulates a dirty engine part being cleaned. We have already tried to create this by stitching a series of still images together, however, the end result was unacceptably jerky. The video producer said it might be necessary to 3D render it get the smooth transitions we are looking for. I have attached samples of some of the still images to show the transformation. There is approximately 80 stills
