Just a FYI: Audiobooks through Audible are available in multiple regions/countries such as Germany and the UK, in addition to the USA. I believe it happens automatically (my publisher deals with that end), but I also believe that the vast majority (if not all) of the titles are narrated in English, at least at this point in time. The links can be found by googling 'Audible Germany' or 'Audible UK' etc.
I know they're available for sale in lots of countries, and I know they're produced by publishers in those countries... but has the ACX program expanded to include self-published authors from non-American countries? ETA: I just checked - looks like it's spread to the UK, but not any further.
If English is your not main language then it is suggested to get your translated from experts who are highly professional and not just from anyone who knows both the language.
