Hi, i am looking for a game developer that can develop for me simple HTML5 games that are like leaderboard based or time based. Games are like https://www.gamee.com/game/karatekid2 , https://www.gamee.com/game/5IsYwla . These games will be used in my website and embedded in my mobile app. Simple ones and I need roughly 30-50 of such games.  Please let me know the quotation, and time needed, thank you.
