AI Video Creator for Pixar Style Animated Movie Trailer

Hey! I am seeking an experienced AI video creator or a video animation expert to transform a 150 second pre written script into a Pixar Style animated movie trailer for a marriage proposal. I tried doing it on my own using mid journey but it was harder than I imagined. The person should ideally have a key eye for detail particularly in maintaining character consistency (the biggest challenge I faced), and must adhere to strict data privacy protocols as I'll be sharing images. I think someone who has worked extensively with AI generative tools will be a good fit.
