Translation of null in Spanish

I usually charge 15 dollars per hour, but I don't care very much for the hourly system. I can also help with corrections and suggestions, but only if the original text is a serious translation and not an automatic one.
I will answer your mail during the weekend. Please translate the same text to Hungarian. I think it is easier to write. We can do the same with Spanish. Just note that the context needs to stay the same.
Nevertheless, I was looking forward to the flight. Thirteen hours in the air has something exciting in itself. You can watch movies, sleep, read newspapers and rest. Normally, we always under stress.
