Voice-Over Actors for MFA Student Documentary film

I am making a short documentary that contains 3 very short (a paragraph each in length) voice-overs of letters.

I am hoping to find individuals to provide these voice-overs. I have sound recording equipment and can go to wherever is convenient for you on campus to record your voice. I would need no longer than 15 minutes with each person. I am making this film with my own resources, but I could provide $20 per person as a fee to compensate for your time. Your name would also, of course, appear in the film's credits.

I am ideally looking for 3 female voices that are distinct from each other. I would also be interested in recording 2-3 male voices that would only be reading a couple sentences of a letter (for these, I would only need 10 minutes of their time, and would be able to provide $10).

Please let me know if you are interested. I will just request a short audio recording of your voice ahead of time (this can be a simple recording with your phone or on your computer- I just need to make sure the sound of your voice fits in with what I'm looking for!)

Thank you!
