Translation of Fastenzeit in German-English

I made a mistake regarding the information of the yield, you were right. I do not know whether the software had a license, I will let you know once I speak with my employer (tomorrow). Hasta luego.
After that I expect that you do the same. Write me a text in English and the same translated to Spanish. This way we will learn all directions. We will be able to compare the texts and learn.
Is there a way that I could test your Spanish and German lessons? Quality is very important to me. Can you send me a lesson electronically (by email or word)? Maybe you have your lesson ready.
