I just took a half dozen notes on this. :)   When small businesses like these get an EIN and LLC for next to nothing they can build corporate credit rapidly through religiously following a little bit of free or cheap online education (then executing on it, like using the right trade lines). It happens all the time. Long story short, after almost wasting $6k USD on some reseller of the BS business credit building platform called Credit Suite, I got back all but $500 and reinvested $5 at https://businesscred.it then got credit card with 10x the balance of my best personal card.
