Amazon and Gumroad for Ebooks

Amazon and Gumroad both have the ebook version for them. Do you offer your book in any other formats like maybe a paperback or an audiobook? I'm not doing it mostly because for there are only four countries, US, UK, Australia andI think Ireland was out of and self-published and Audible but from all the other countries you need to pass through a company like you need to have a professional company that does that.
