Does your company you work for provide any help for this. My neighbor works at home and his company setup all of his internet for him including VPN etc...
If this is your legal verified and licensed company should be write-off for you perhaps...
Of course this area is fed by a cable company but his company had him setup with the fasted and biggest data package the cable company had at no cost to the neighbor.
We get by just fine on around 3GB MONTHLY data plan here but its only for checking in with the kids, paying a few bills, and doing a minimum surfing of the internet using a VERIZON MIFI DATA PLAN.
3GB a day is going to be hard to find nowdays... Curious what you come up with...
