Hi, greetings from Serbia.
As I see no one from Croatia ain't bid on your project still so I have to offer my services generously.
I can't handle it not to do. If you know what I mean guys. :)
Serbian, Croatian, Bosnian and Montenegro language are 100% same.
Macedonian and Slovenian are different approx. 20-30%.
Serbian and Slovak language differ by 50%.
So with Croatian, I can help you.
Kind regards
Bojan
