There are two options; Google Play, or the Draft2Digital publication targets.
Google Play isn't available globally (though they intend to be, based on how the publisher interface sets up billing regions!). So you might need to try one of the Draft2Digital targets. Kobo seems to be a good fallback choice for availability though not for avoiding DRM.

Update 2019-01-29: Amazon changed their agreement with Draft2Digital to require a whole lot of information transfer to Amazon. I have removed The Human Dress from sale at Amazon. Still up everywhere else it was available. (And has been added to a bunch of library services.)
