I can save it as an image file that includes no background which I imagine would be best.
Would having no country lines be more friendly maybe? Suggesting the world is more united instead of divided.
For fonts would you rather I leave that up to you and it could be separate from the logo? You can adjust fonts as easily as I can. Lots of free fonts exist too, like at websites such as dafont.com and fontspace.com
If you aren’t satisfied with any then I can try to come up with some font options for you.
