Hello! I'm the right person you're looking for this work. You can see a sample of my voice on my portfolio and, in a couple hours, I can send you the sample you are asking for on a homemade version.
What I mean is, once you have show some interest on my work and hire me, I can record the final version on a professional soundroom (which I must rent) to assure the best quality file.
I need you to contact me through the chatbox to send you the mp3 file.
I'll be awaiting for your contact.
Have a nice day!!
