VFX Editor Needed for a 32-Second TikTok Video

I am looking for an experienced VFX/video editor to edit a 32-second vertical TikTok video. I need the final video to be completed and delivered within 7 days. For approximately 1.5 seconds, the editor will need to realistically add an adult woman wearing a swimsuit inside a shower, seen from behind. Only part of her body may be visible if this creates a more natural result. The woman can be created using AI or added from an external PNG/image. The final result must look realistic, natural and well integrated with the camera movement, lighting and environment. More details, reference files and exact timing will be provided privately. Please apply only if you have experience with realistic compositing, AI video editing, masking or motion tracking.
