Превод - Немски-Английски - Gewundert...

Because there were some mistakes, i changed it a bit, but I'm not quite sure if this the actually meaning..

please, is there someone speaking GERMAN, who can visit and help this translation?

Yes, sorry!
Well, the first paragraph seems strange to me because of two points: "sich wundern" ("sich gewundert haben" is past tense) means "to wonder, to be surprised", not "to surprise oneself". And I wonder about the "finished", in the German text, there's just "has spoken" ( or "spoke", or with the verb "enunciate" ), but my native language is not English...
The subordinate clause ( which, in my eyes, must be completed to "on WHICH the canvassers of Saxony REACTED with 400 location offers" ) refers to the "inquires", not to the "inspections".
Besides, it's not bad translated, esspecially "to lead the way to" is, in my opinion, a nice idea to express "etw. vorangehen".
That's all I can say, hope I could help.

thank you Rumo!

I've changed the translation according to your suggestions. I'm going to validate it tomorrow, if it sounds good to everyone...

Thnx!
