Translation of Kellnerin

I need to write you one more sentence. This is what my teacher told me and the German language is so difficult. So please, as a last favor, would you please write the sentence for me in German?
In addition, I want to inform you that I found a possibility to deliver a more Spanish lessons from Vocabulix. To my knowledge, the lessons are excellent and a great base for the Spanish training.
