Batch Photo Background Removal, Video Merge

I have two separate but straightforward tasks that I’d like handled together.

First, I need the backgrounds removed from a batch of product photos—somewhere in the 11-50 range. Clean extractions with no haloing are essential because the final images will sit on both white and colored website sections. Please return the files as transparent PNGs plus the layered PSDs so I can make future edits if needed.

Second, I have a short video clip and a separate audio track that must be merged and synced perfectly. The finished file should be delivered in 1080p MP4 with the original video quality preserved and the audio mixed so levels are even throughout.

Deliverables
• 11-50 background-free PNGs + layered PSDs
• One merged, synced 1080p MP4

Please let me know your estimated turnaround time and any questions you may have about formats or specifications.
