The 50GB plan is the largest residential plan there is.  There are business plans that are larger, however.  You should be able to see what Business plans are available to you on the main HughesNet Business website.  

As for whether the 50GB residential plan is available to you, and what it would cost, you should be able to see on the HughesNet MyAccount website.  Sign into the MyAccount website, then hover over Shop/Upgrade and click on Plans & Pricing.  If you see the 50GB plan there, you should be able to click on the orange button to show the pricing and availability.  It's a fairly seamless upgrade, just changing your plan within the service you already have.  It doesn't extend your contract or anything. Keep in mind, though, the the price would be prorated for your current month.

Hope this helps.  🙂
