Modify only the design and the language game Ikariam

Well I have the game ikariam complete, running 100 % and no errors, what I want is a change in game design and the exchange of Russian to English I called, only that, the game will continue with the same schedule and same rules, the more it will change only the design, instead of being in the Empire is a land like the map of DotA, and the increment of some heroes of warcraft, orc and elf for example, only it will not have a job programming because the system is now all ready, just want to modify the design, and add a chat just that. I will pass the code for the programmer to work with me to change.
