Looking for a html5 game developer to help build arcade/gaming portal

We're looking for someone who can help us build a html5 based mobile gaming portal/arcade. We're hoping to have at least 30 games (if not more) including replicas of all the most popular games around (if possible) such as flappybird, angry birds, candy crush, doodle jump, colour bounce, tap revenge, ridiculous fishing, temple run, tiny wings, fruit ninja, cut the rope, etc.. Completely open to buying clone games and game packs from the likes of code canyon or any where else. However we'd like to ensure that each of the games has a few features so will most likely needs some customisation. Customisation we'd be after would be retaining the highscore for the user, single game leader board, potentially a cross game leader board, some admin stats to see most popular games, most active users etc. Open to whatever framework the main site is built in. If you have design skills to help with this, that is a bigger bonus. The primary use will be on mobile so responsive is essential. Ideally some thought for language translation would be really great too as we're looking to serve the portal to multiple countries and languages (however this isn't essential) With your application please include a bit about your history, potential time frames, rough costing and any questions you may have. We are on a bit of a time pressure to get this sorted within weeks so please bare this in mind when getting in touch. We're open to either being fixed price or hourly project
