Freepbx Hosting at or near Guam

I have a client setting a new site at Guam,
I’m looking for a reliable freepbx hosting company at Guam or close to Guam.
Appreciate any recommendations!

Thanks

What’s the basis for the requirement? If it is resilience against earthquake, or military action, I doubt that anything not physically on Guam will be close enough.
