Browser Text PHP Turn-Based MMORPG (Similar to BaneofSin.com)

I would like a browser text turn-based PHP game built similar to BaneofSin.com. Please do not bid if you do not know how this game functions. The theme of the new game is steampunk so should have steampunk elements. There should also be an admin section which should be user-friendly such that someone without complex computer knowledge can operate the website, such as adding bonus turns. The website layout and functions should be coded in the simplest way, and should be upgradeable easily in the future (Such as changing the graphics/banners or changing names of units etc)
