Hi,
It seems you are from France, if you speak french let me know as I am also french and we can therefore communicate more effectively.
I am from Montreal, Canada, would be please to develop your iPhone game. Since I do not have reviews (yet) on this site, I'll be happy to create a demo for you before you choose your freelancer, just let me know a bit more about how the game is played (basic rules, etc..). Therefore you can see that I have the competence before you make a commitment.
I am fine with payment at the completion of the project.
Best,
Christopher
