Apologize, Everest is no doubt a scam and mentions timeshares. I looked up the website that you list for Everst and it is a very generic website that has a lot of mumbo jumbo but really doesn't say a whole lot. And it certainly doesn't state anything about timeshares.
The name doesn't matter. What matters is that they cold called you with an offer too good to be true, their website is nine months old, they have no track record, their "direct number" for Utah is a VoIP Internet phone line (meaning they could be calling from anywhere in the world, not necessarily Utah), and their website doesn't even list an address.
If you Google the address they had on their "offer" you will likely find that the address doesn't exist, it is a large office complex yet they do not list a suite number or it is simply a drop box. These scammers do not set up shop, they often randomly obtain an "address" in any city and then obtain a VoIP number with a prefix to match the city so people think they are legit.
Edited to add:
another way to tell a scam is the website itself. They use both Everst AND Everest on their website for their name. They probably just misspelled Everest when they set their scam up. You can also Google a sentence from their website to see what else comes up. I did and at least three other companies use the same paragraph as the one who contacted you. Either they simply copied and pasted from a legit company or they have created a number of throwaway websites for their scam.

Just found out the paragraph your scammer is using is the same as another older scammer called the Beikman Group. Probably the same scammer. Here is the thread.

I also checked the IP address for Everstgroup.com and it comes back to ARGENTINA.
I think that sums the scam up pretty well.
