Translation of Klinge

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?
Please postpone by three days to one week. I am abroad, and Loraine can't come with the baby. We are available from august 31 until September 23 (except September 16) where we have other commitments.
We have cut the description though, since it was too long. However, we would like to change the description again, by adding a geographic spot in it or telling the user that it is E-learning.
