As it relates to one specific example on this list, I live in Leipzig, and in East Germany in general, it is nearly impossible to speak English on the phone in order to arrange these sorts of things, plus so many places do not accept Visa (only Maestro/EC card). So coming from the US, you are especially unprepared, and being able to pay OP in USD to have things set up that require German knowledge + lots of euros = huge benefit in not losing money via wire transfer and not needing to know the language in advance.
