If you're still looking for voices for movie trailers. Send me a short script and I'll send you a high quality MP3 as an audition. And let me know if that's what you're looking for.
No charge in exchange for credit. Like to help out younger filmmaker and YouTubers.
In the future, if you are looking for voice actors go to the Voice Acting Alliance forum. Brilliant place for people to find voice actors. Its filled to the brim with talented people. Its how I got involved in my first projects.
