Languages - guidances,ways to learn.

By the way, what about tools which I mentioned?
Any recommendations or experiences?

To be honest, there are not so many decent translation services. I was using it only several times, you can check here for  services https://isaccurate.com/resume-translation-services the last time in a similar situation, when I was needed a translation help I was looking for resolution exactly on that page! I can`t recommend any another services, cause translations are peculiar thing, and it can be done so bad if you choose bad service to do it
Hope it helps
