Canceling Solar Panel Contract with Sunrun

Just got off the phone with someone from SolarEquitiesSolutions.com. They say they can guarantee getting me out of my Sunrun solar contract (the one that used to be Vivint Solar). The quoted fee is $9,000, and they’ll send over the contract before I commit.

Anyone familiar with this company? Is this a good deal or does it sound sketchy? Looking for thoughts!
