Vietnamese Dubbing project

Hello,
Greetings from verbolabs!

We have a new project in Vietnamese, in which we require Male and Female artists.

a. Languages: Vietnamese
b. The file has three sheets. The first two sheets are the scripts to be dubbed, and the lines are highlighted in yellow. Sheet 3 contains the list of characters, with the gender and age listed as well.
c. The project has over 20 characters (21 to be specific), nearly 600 lines.
d. Since there are about 21 characters, about 5 are main characters with over 500 lines. The other characters have limited lines (3-5 lines only). As such, the client agrees that we can re-use the voice talents for the main characters.

We will be using 5 artists for main characters and 4 other artists who will dub for all the remaining characters. So, we have considered 9 artists for the project.

Duration of each main character would be 15 min. approx. and for extra artists it would be 1-2 min.

1. If you are doing 15 min ,what do you charge?
2.If you will do 1-2min, what do you charge?
