Is your project open source, and do you have users willing to do the traslations?
I use POeditor.com, which you can apply to use for free if you have an open source project. You can create a public joining link then people can contribute translations for you.
Then just export the po/mo files for your project.
This relies on you getting users to translate, but if you put a link in your readme you may not have too much trouble.
