I develop game for Windows, iOS and Android with Unity3D. I developed some game with Photon (Multiplayer-Realtime), Google ADS, Google SDK, Unity ADS, Facebook, Twitter, In-App Purchase, VR, AR, mySQL (for store data online). I do not create 3D Models and UI for your games request. I can develop a demo in less than a week if it might be of interest. I am Italian, I'm 20 and I use Unity3D for 3 year. Remember that your mind have not limit! Thanks.
