10-15s Facebook Slideshow Video

I need a concise, professional slideshow—10 to 15 seconds long—built from the photos and short text lines I’ll supply. The finished piece has to look polished on a Facebook feed: smooth transitions, on-brand text overlays, and subtle, royalty-free background music that passes Facebook’s audio checks.

Here’s what you’ll receive from me:
• High-resolution images
• Exact copy for each overlay
• Brand colours, logo, and any font files

What I expect back:
• A sequenced slideshow with clean transitions and timed text
• Background track mixed to FB loudness standards
• Final MP4 in an aspect ratio suited to the feed (1080×1080 or 1080×1350)
• One round of minor revisions
