Rebuild the audio cleanly

We have a 15-second medical advertisement and would like you to rebuild the audio underneath the locked New England visuals. We will provide (attached below): - The locked New England video. - The existing New England voiceover file. - The Dallas video as an additional creative reference. Please do not attempt to extract and relocate the existing sniff. Rebuild the audio cleanly: - Create a realistic first nasal-spray sound and align it with the first visible spray action. - Create a realistic second nasal-spray sound and align it with the second visible spray action. - Create one subtle, natural sniff. - Use the current New England version as an approximate timing reference but place the new sniff where it feels most believable with the actress’s movement. - Add the supplied New England voiceover. - Add an appropriate music bed and create a clean final mix. The desired opening rhythm is: Spray → “One spray.” Spray → “Then another.” Sniff/visual symptom → “Still congested?” The effects should support the voiceover without competing with it. The sniff should sound subtle, dry and human—not exaggerated or comedic. The music should add energy without overpowering the voice. Please do not change the visuals, text, logo, color or end card. Minor visual retiming of no more than a few frames is acceptable only if it clearly improves synchronization. Please provide: - Final New England MP4 with the complete mix - Music-and-effects master with no voiceover - Music-only stem - Spray-and-sniff effects-only stem - Editable Premiere Pro or DaVinci Resolve project with the linked assets packaged - Confirmation that all music and effects are licensed for paid advertising on Facebook, YouTube and OTT All audio stems must: - Be WAV files at 48 kHz/24-bit - Begin at exactly 00:00 - Match the exact duration of the video - Remain synchronized when dropped directly into the timeline - Have no clipping or heavy limiting The music-and-effects master is especially important. After approval, our internal team needs to be able to place a new market voiceover at 00:00 and export the localized version without rebuilding the sound design. Please include two final reference versions: - Version A with a subtle sniff - Version B with a slightly more pronounced sniff This is a $100 fixed-price test, including one reasonable revision.
