I recommend to send either a .doc, .pages or any other open format file with your text. I do not like to use .pdf files because I can not change anything in the text. Also .txt files are sometimes tricky.
Write like you speak! Writing for the ear is more informal than writing to be read. You may find that it improves your style if you imagine that you are speaking to someone while you are writing. When you write like you speak, you will naturally use smaller words and shorter sentences
Please add some directions to your Voiceover script as I need to know what kind of style you prefer. If you have ideas of the speed of the recording please let me know in advance what the maximum or minimum time of the recording should be.
If you want to use the recording for a video sync, please check your script before sending whether the timing is ok. If yes, it is advisable to give some directions for the timing. If not, please feel free to ask for an extra job to rewrite your script.
MP3 is a lossy codec, meaning audio encoded in it is stripped of extraneous information to reduce its file size. WAV is an uncompressed audio, meaning it contains a lot of audio information — and audio quality — but results in a bigger file size. Please let me know what format you prefer...
