Work on existing Flash Mobile App project

We have an existing project that we finished 1,5 years ago. It is a childrens book app that runs on iOs and Android. Online there is a database in which all pages, animations (we invented our own animation language), translations, in app purchases, etc. are stored for later use in the app. After download it stays in the app. The app has voicerecording capabilities, live chatting, multible books, little games and more. We are looking for a Flash programmer to help us in several stages of our new project that will be based on this app. So we remodel the app in a different style and we are going to use different characters. For the rest it needs to be the same. Because the app is possibly outdated (because we made it 1,5 years ago) we think we have to look at the overall performance if nescesary. The project will run for a longer time, so please react if you are looking to work yourself in this project and work on it for the next years to come. Only if above is aplicable for you, we will brief you deeper into the project.
