I do several Gigs of Fiverr for voice overs. This is your 1-day turnaround spotlight! For 30 seconds and $5 you get a 24h turnaround. That's crystal clear audio that is also listened to and re-recorded if anything doesn't sound just right by me.
You can have up to 1 round of revisions. Be clear with the direction and intent and provide examples for your best bet of hitting your deadline.

You will get an MP3. Get the Extra for the WAV or AIFF.
