Translation of Unteroffizier

Thanks for the message. I hope that your friend here in England will soon be feeling better. If you decide to come at another time, I would be very pleased to meet you here. You can sleep at my place.
I met the company last autumn, because the site's traffic is getting pretty big and they invited me to a workshop. They have convinced me that I have to put their logo at the top of the page to maximize exposure and this was a big mistake.
