client and server for a card game with lobby and payment options -- 3

Hi, the project is an online card game (similar to poker) with lobby where people can register/login. The users can deposit money in there account, so the software needs to be very very secure. The card game needs to be playable in a browser on desktop and phone/tablet. There must be a backend where whe can adjust settings, create rooms (different stakes) and see other statistics. The algoritims needs to be created by you, i have the rules of the game in english, these needs to be inplemented by you. This is only the first version. after that we have a new budget to further develop the platform. It will be an ongoing process, if the job is done good you can be the lead developer for this site. I only discuss if you have proven experience with card games Thanks
