Translation of desinteressiert

I thought it was great to hear from you. I would love to help you to learn Spanish. I'll write in English and you tell me the Spanish translation. I think that you're good enough for that exercise.
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.
I would be glad if you can tell me more about the United States, of course in German! Maybe we can talk again when you're back at home, what do you think? That would be a good practice, wouldn't it.
