I’d like to note that there are a lot of cheap, reliable providers that support BSD, either with KVM templates already, installation with an available ISO, or many have custom ISO where you can upload or give the URI to any iso you wish to use. Obviously this will usually be KVM virtualization.

Some providers off the top of my head:

prgmr.com (now tornado vps apparently) - long-standing provider - they used to have netbsd dom0’s but now it’s all Linux based it looks like so appears you have to netinstall netbsd in your vm now)

buyvm.net - reasonable pricing and have bsd available to install (can’t remember if template or iso ready to mount/install)

https://www.netcup.eu/vserver/ - excellent value / been around forever (they offer custom iso)

I will add more here as I think of them..
