I have an online card game (with real time with sockets), that can be played on windows, Android, and Web. I need the same game to be ported to iPhone/iPad. Characteristics needed: - User login. - Different Chat rooms. - Private message between users. - Dialog to create new game (with chat). - The game board (with chat to). You can see the game board of the web version of the game. - Optional: push notifications for news, for invitations to join a game (when you are not connected). - Optional: adds. I already have: - Database. - Protocol. - Server. - Graphics. I will provide: - Graphics: Cards, etc - The protocol. - Functions (in C or Java) to help with the game rules and protocol. I don't know how much it will cost to do that. Can anyone help me?
