Everything about the story is currently in my head, so I do think adding a co-writer to the team would be a wise decision... A first mate (or two), so to speak :) I understand this is an... odd position to fill, but please bare with me.
I'll be sharing my ideas with you first and foremost, and I hope you'll do the same with me. Work with me to make my ideas the best they can be! If you're a harsh critic, trust me, I can take it.
For your 'audition', please, include any of your previous works that you'd like me to read. I look forward to reading all of them, and I implore others to do so as well.
