Depending on your exact location, Starlink may be available.

Alternatively, a hosted solution might work.  In a hosted environment you log onto a remote desktop that connects to a remote server.  Connectivity between the remote desktop and server should, (if properly configured) be fast.  If you have a qualified IT person who is familiar with AWS (Amazon Wed Services), they can set up and environment similar to the Intuit host service (Actually Intuit outsources to RightNetworks).

The biggest potential issue I see with remote services in a remote area is physical printing as large print jobs can use significant bandwidth and may time out.

No matter what you do, please store encrypted backups in more than one place.  Local is great for convenience, maybe your home to protect against regional problems (floods/fires), and definitely in the cloud so you can have a plan for disaster recovery.
