Professional Voiceover for Technical Instructional Video

I'm looking for someone to use an AI voiceover service to add a professional realistic sounding voiceover to an instructional video I made for an installation guide. I have the script I only need the voiceover to be applied to the video and timed appropriately.

Here's what I am precisely seeking:

- A professional tone that compels the audience to follow the given technical instructions.

- Voice should sound like a real person and be timed appropriately to the video frames
