Greeting,
Thanks for the description and taking time to read my offer
My name Khairil from Indonesia. First of all let me summarize what need to be done :
I want to suggest that you would like to hire multiple native Indonesian for this project. 500 hours worth of voice files seems to be impossible to be completed by solo freelancer, in addition as far as i know there is no Indonesian agency operate and offer their services in this platform. So, hirirng multiple native freelancer will be an option, i think.
I am quoting $10/1 hour voice file. Please share more detail.
I know there will be some detail of the job desc that need to be discussed in detail. Feel free to reach me out at anytime, i will be more than happy to discuss it immediately.
Can't wait to work with you,
Khairil
