Looking for North American male voice. 120 seconds.

Hi good day. I'm looking for a North American male voice to produce 120 seconds audio. We only need your voice to mix it with a video animation. Please, show us some voice samples. If you have medical topic samples, that would be great. Write at the beginning of your bid "I'm not a robot because i can feel" so we know you are able to work on the project this week. No Indian or Pakis. Thank you!
