Develop Android and IOS Game

Hello, iam looking for someone who can create and also develop a game regarding the topic "planting trees in forest". The Idea: The core of the smartphone app is to be a strategic game in which the player is to manage and maintain a forest stock over a longer period of time. He learns how natural forestry, research, environmental protection, hunting, sport and recreation are combined with modern forest management. A good starting point as the strategy game might look like, is the Webgame "Caledon" (can be found here: [login to view URL]) In addition, during the game, the player receives professional advice from virtual professionals and thus learns the contents of different forestry professions. In short quizzes, the player can have his / her newly learned knowledge checked and receives the respective professional title. The smartphone app should also bring the user into the real forest and motivate them to explore. Depending on the level of education, he is asked to discover the tree species of a forest in his environment. But this will be after the "normal" gameplay". I need a whole concept for this game for IOS and Android Devices, with all together (UI, Sounds, Development, Ideas) The Game Caledon is a good template for it but our game should be better and should look nicer, the educational aspect is very important. Please send your estimated time, costs and ideas for this. ONLY DEVELOPERS WITH A LOT OF EXPERIENCE AND REFERENCES YOU CAN SHOW! ALL OTHER OFFERS WILL BE DELETED! Tank you! Kind Regards
