Build a Text Game Website

I would like you guys to give me your quotes and time for completion based on this game: [login to view URL] Basically if you were to write a copy of this game with lots of stuff happening in a revolution (30 minutes). Basically, there should be stuff happening at each set period of time (for example 30 minutes). And everything is based on that. When you build tanks, its spread over 12 30min cycles. You get income based on your buildings every 30 minutes, and its the same 30 minutes for everyone. Every time the clock hits :00 or :30, its update time. And the game consists of some mechanics, such as having air fleet with own stats, military fleet, nukes and aims, player types influencing on income rates, and so on. Basically the game is easy to lay out, but its a grind to put all those systems to place. I would like you guys to see the game and tell me how much would you charge to build a clone of it. Then we move from there.
