Have you considered Starlink (Elon Musk's satellite system). It has just announced a plan for businesses that they call a "premium plan" which sounds like it might suit you. We have Starlink at our winter location and love it.
Starlink Business
Yes, I have.
I've been on the residential list for over a year, maybe more like 1 1/2 years. And for the business service, I've been on that list for a long time as well. The biggest problem I have with Starlink is there is no way to find out when the service is actually going to be available in my area.
When I first signed up for residential service, their website said sometime in the middle or end of 2021. Now when I check, the website says they are at saturation point in my area and they will notify me when there is availability.
Starlink Business says they will start shipping 2nd quarter of 2022, which could mean as early as next week or maybe never. There is virtually no way, not that I've found anyway, to find out "when" the service will really be available.
Somewhere along the line, a decision has to be made to either continue waiting for a service that has no verifiable installation date, or move forward with a solution that has an actual delivery date. And at the end of the day, there isn't much difference in price between Starlink at $500 a month, and Frontier at $600 a month.
One last thing, when considering the Starlink solution. At this time, and with respect to data caps, (which is a HUGE concern) Starlink advertises that there are "currently no data caps". But Starlink is a satellite solution, and all the current satellite solutions available today use data caps. There is nothing to indicate that Starlink won't also go that route when their system becomes congested. And if/when they do, the solution will becomes ineffective for our needs.
Data caps are actually one of the primary reasons that our current provider, ViaSat, isn't a good solution for us today. ViaSat (business) delivers 100mb down, which is more than enough bandwidth for the needs of a small RV park like mine. But with a 150 gigabyte data cap, the solution becomes ineffective as the first few visitors each month can consume it quickly, leaving the remainder of the guests with little or no service for the remainder of the month.
