Hi, I'm a unity3d developer with more than three years of game development experience. I've worked a lot on server based resource management games. I've worked on two hayday clones. I can show you my previous work. I've experience with sqlite, json parsing, 2d UI development, NGUI, server connections, isometric grid management, path finding and character controllers. These tools/techniques cover most of your requirements.
I'm easy to approach as I'm available online most of time.
Contact me for best work.
