Hello Mr./Ms.,
I am interested in your job offer.
I am a member of a small team, you can view our profile page so that I don't write much here. In short, we are hardworking people and persistent in achieving our goals.
We are fluent English speakers, both grammatically and vocally (if needed).
A friend of mine has made a software for text to speech, which is pretty good and includes the language needed. Therefore, for a very cheap price you can get "voice over" for your video.
We will provide you with many examples, as much as you want, so you can see if it fits your needs.
Hope to hear from you, thank you in advance.
