Here are several of AmpOnTheAir's favorite sites:
Voices For All (VFA) is based out of New York. This company was my first resource for my venture into the voiceover world.
A Pay-to-Play site that is one of the avenues for marketing my voice.
An awesome site headed by voiceover expert, Terry Daniels, who started this club to help "newbie" voiceover actors. If you subscribe for a reasonable fee, you get a wealth of knowledge on how to get into the VO business.
Leah Frederick: Leah Frederick was my first instructor, who introduced me to the world of voiceovers. She is one of the coaches at Voices For All, and continues to influence my desire to pursue a career in the voiceover business.
MikeElmoreTalks!: Mike Elmore is an amazing voiceover talent, instructor, coach, director, and producer. I was lucky enough to experience Mike's passion for all the above when I took the Voices For All-Master Class. If he were to teach another VFA course and I had the time & funds, I would be there in a snap!
