Xamarin game developpement

I want to develop a game on xamarin ( so to be runned on android and ios), so I am looking for a good designer and developer to do this task. Expected delivery: * wireframes (12) * the game graphical identity (screens, icons, pictures, font, backgound of the levelx3) * a level creator ( so non techie guys can build the levels). It will produce an XML file that can be attached to the games to add new level. * the level creator is an ASP web application, that displays an emulated phone screen where a user can select the background , road block ( 4 blocks ), decoration ( small tree, big tree, small group of rocks, big rocks), enemies (waves) , hangar and initial ressources. * source code of the game including at least 2 levels created by the level creator. * the freelance must be able to communicate vocally in english because we need to plan at least 2 video meeting.
