Hi,
my boss asked me to translate a prefabricated phone conversation from German into Englisch.
Now that I finished, I am very doubtful about it and I think there are many mistakes.
If anyone of you has got some free time, I would be very happy if you take a look at the text.
Just to check if the expressions, the word order times…etc are right.
For some expressions I wrote two options, you can delete the wrong one. (example: start of the construction/construction start)
thank you very very much!!!!
