So, you need someone who's experienced in play-writing. That's me. I've done work for video games, and actual plays- admittedly, college level, but they were performed. I know the formatting, I know the styles generally needed, I know the business. It's not just words you need cut down, I can say that.
You need someone who knows how to speak curtly and yet get across the same amount of meaning. That's me again. Not only have I done the prior two, I've done PR work for media on Twitter. You learn a lot of tricks paring things down to 140 characters.
Lastly, you need someone who's speedy. Guess who? Right again. I've got time, I've got skill. You want this done quick, no doubt. They like to say 'quick, fast, cheap, pick two.' Yeah, well, miracles of modern technology say different.
You want all that, you pick me! I'm not gonna tug you around and mess with you- I don't have TIME for that. You need a skilled editor, I'm your man.
