@ Ann: That's totally up to you. You can "Browse Freelancers by Category-Design and Creative-Voice Talent" to research what 63,000 + on the Upwork platform within this category are charging. I could have provided you with the link but believe it's in your best interest to research and learn to do these things yourself. Best of luck to you!
Just out of curiosity...
If you're a beginning voice over artist, why does your education list 2 years working in the voice over industry? Do you have some voice over experience (yes, I understand that two years can be considered to still be in the beginner category)?
Also, I highly recommend you also add samples to your profile.
Good luck to you!
