I'd love to see what you have on the project so far concept-wise and work out what it is you're looking for in terms of writing — unpaid is fine. I'm interested in seeing what you and the team have completed before!
You can contact me at aaronjgpark@gmail.com . I'll make a Skype down the line if I decide to contribute to the game, since I'm assuming you do a fair bit of communication there.
