Game development

Hi, I want to get a game developed on android platform with all hardwares of HTC and samsung supported with all there features like shake, touchpad etc... The version supported will be 1.5 to 2.2 of Android. The game is classical snake and ladder with few innovations. The screen of the game will be in English Punjabi and Hindi language. The person whom I will chose will have to sign non-disclosure agreement of no further use of the code for next 12 months as well as transfer of the complete code to us. He will have a service contract of next 45 days with maximum working hours subject to 75. This period will be solely for the purpose of any bugs fixing or slight modifications which might come across once I see the final outcome of the project, Payment will done in milestone preferably by escrow. For each milestone payment will only be released once code till that stage is transferred to me and properly configured on my local emulator. The service provider must have a prior experience to such coding and few apps preferably games listed in android market. This is a recurring process from my side and the relation will solely depend on the nature of the service delivered. The most important thing, I will hold you responsible for all of your time line.
