Translation of picea

I try to learn English as much as possible so that I can travel next year to the United States. I would agree to your proposal but I also need to find good teachers. My goal is quality and speed.
I think I have told you that I won't charge you for this kind of help. I looked at the sentences and I found them a little too long. They were good, but I understand why it took you so long and I think the point is too keep the shorter.
So you are getting used to write in Spanish. But I think you should not worry, as your Spanish is good and you understand everything. You'll enjoy it a lot, once you meet new people who speak it.
