It’s unusual for somebody to knock on your door. Maybe they are just really hard chargers. Or that may be a sign of “we need to get this done immediately” for a number of legitimate or shady reasons.
In terms of finding somebody to talk to, it depends on what you want to search for…there are a number of service providers in the “Directories” listing on the top right of the page. From an engineering/evaluation side you may want to contact Tracy Lenz from that list. Don’t know her, or any of the others, but she seems pretty solid from what I have seen on here.
If you just want to say “I own X and was offered Y” I can probably tell you where your offer stands relative to the current market, I know a little bit about Lea County NM. But for all you know I am a 13 year old taking a break from playing Fortnite.
Cheers
