Build a browser based game similar to Agar.io game

Hello, for this project i'm looking for a experienced developer in html5, javascript and node.js to build a 2D multiplayer game similar to [login to view URL] for browser. The game is similar to [login to view URL] because it's a multiplayer game in 2d with simple character and one map only (A grid), the game is very easy to play by using the mouse only and the design is very simple. However the logic of the game won't be the same but the concept of eat to grow is present. The game can be played via every browser like chrome, firefox, opera etc For this game i ask the same languages used for [login to view URL] and [login to view URL], it means : html5 + javascript + node.js (With [login to view URL] for the multiplayer in realtime) Forbiden to use Unity 3d. The homepage is similar to the one of [login to view URL], for the players just need to enter their username to play, no sign up or log in. This include making the game, all the designs and implement the game on the server. I have all the models of the games in png. There is a homepage and the game. There is one map only and one character and one move. If the project is well done i will hire the developer for the mobile version and some others games project similar to this one. Chat with me for more details.
