Hello, here is our portfolio http://meliorgames.com. Our company MeliorGames is providing highly professional business app and game development services for iOS/Android. In our portfolio there are only our own games presented, however we have many other successfully completed outsource projects (business apps and games). We have experience in building such applications and we can complete and fix bugs in your app, though for estimating the cost and timeframes we need to check it ourselves, define the problems and see what should be exactly completed. If you are interested in cooperation, please contact us we will discuss the details. We are ready and able to help you with your project. Thanks. Best regards
