Moved And now I can’t get Xfinity help please

So I moved to a new house. I live on a private lane and Xfinity doesn’t service my area I opened a ticket to get a survey they’re coming out in the next 7 to 10 days but they lady that called me to set up the survey said it was gonna cost $21,000.00 To get service to my house. My question is is with all the Covid and stuff my kids do online schooling is there anyway I can get some sort of help for this they really need Internet and I also need it to run my business.
