Car Promo Vertical Resize

I need my existing car-rental promo, built in Adobe After Effects, converted from its current landscape layout to a 1080 × 1920 vertical format. Every slide, graphic, and piece of footage has to be repositioned or rescaled so it fills the new frame naturally without letter-boxing or awkward cropping...
