GBScammers! They are fake. Based in Pakistan. Pretending to be in the US, Canada, Australia and the United Kingdom. They use virtual phone numbers while sitting in Pakistan to make fool all the customers. I used to talk with one of their members and figured it out within a second. Don't get fool, guys. Edit: "M Cornish" Above: So you feel the same right? They aren't US-based. I lived in Austin for almost 7 years and have friends in there, their office doesn't exist physically. How can we trust them to pay money online? Lol!!! We aren't goons! Edit: Now they are asking for my personal information via Trustpilot. Let me tell you one thing! PRIVACY MATTERS! Edit: 2023-12-17 I just got an email that you guys finally responded to my feedback and it took two years straight. No! You guys are running your services like a call center! People are smart enough now. Even if you call them right now, there will be a Pakistani guy with a typical accent who will be found behind the call. It is very hard to communicate with them. Total waste of time. My review is verified by the trust pilot team because I’ve provided all the requested details to them. Stay away from paramount estimating. They are NOT legit. Scammers!!!!!

GBI 'have been trying out their services… I 'have been trying out their services off and on for past couple of months and I'd say the estimates were up to the mark and value for money.

GBI used to spend a lot of time pricing… I used to spend a lot of time pricing my jobs and was mildly intrigued to explore this avenue of outsource estimating. Luckily, I got their email before holidays and just tried their services for a couple of extensions. I'm pleased with the results so far. I won't hesitate to recommend others.
