Hi WaveZ,
I can understand the skills are not enough for such a multiplayer game in your age, me either. But you'll get better and better in the future :D
We are professional web game developer, and making games since 2013. You can take a look at my portfolio, which contains some of our published games. We are a team with both programmers and artists, and can build a game like that for you easily.
BTW. same graphics are not legal if you want to put your game online, don't worry, we can re-create that for you :)
Your friends,
Sean
