Translation of stepson in German

Mr. Chang informed me that you have a customer that requires similar applications to what my customers have here in Switzerland. I am planning my next trip and I will consider visiting you too.
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.
I had to get used to riding the bike and I almost fell a few times. I drove on the main road and stopped at several little villages near the beach. The locals were very friendly and welcoming.
