I have a lot of experience with unity and my strong suit is in programming. I currently work in Javascript but can easily translate anything into C#. I am currently a little unsure as to what you are looking for though. Are you asking us to create a full-fledged game in an already created world? Or maybe program a piece along side other programmers? The bid that I've placed is currently for about 25 hours worth of work. Once I know a little better what you are seeking, I can give you a better quote. Though not my strong suit, I have had some success with a tower defense that I am currently working on for iPhone. I know how to program basic controls(touch, drag, rotate), and based upon your needs, could also put that into anything you need. I am fluent in English as it is my first language and am available over skype on a daily basis.
