iPhone App Developer (+ Cocos2d)

Hello, I have an existing app and I need to add new levels. I need someone who has experience in writing iPhone app using Cocos2D. I prefer to find the right person and after decide the price for the first simple project, finding a quality coder is top priority for me. After I find a right coder we can go on working together with many new projects (as I have done in the past). I ask if you can answer in PM some questions, thanks :-) Please send me: . one or more links to your app so I can see your work . did you have experience with cocos2D? . what version of iPhone do you have? Do you have also an iPad? . I do not have a mac, what system will we use so that I can test the app (I used different methods in the past)? . generally speaking how much 8 hours of your work costs? . I'll send you all the previous code, what kind of guarantee can you give me that the code will be kept private? Thank you very much, looking forward to read your PM. Have a great day, LucaD
