We often get asked whether we can produce eBooks or Kindle books in Spanish. The answer is yes! What we don’t currently have is support in Spanish, but we’re more than happy to work with you even if English is not your native language: we’re patient and friendly.
Indeed, we can do books in any language supported by Amazon’s KDP – there are quite a few, listed here:

We’ve done ebooks in Spanish, Italian, German, French, and Portuguese.
