Osclass local translate

Hello al freelancer, I have Osclass with 4 languages 2 RTL and 2 LTR. As you know, The Osclass don't translate the local ( country, region, city ) to the another languges if you have a multi language site. Its still ( country, region, city ) in English if you used the site to another languages . What I need. An expert to carry out the process, so that site view the local ( country, region, city ) in Arabic if you used the Arabic languge and view in English if you used the site in English, As well as Turkish and Persian, and I can add and change the names of cities and villages without any problem. This person has already done something similar, Thanks
