If that looks use-italics "really legitimate" to you, then you might be easily scammed. I'm not saying they're not legitimate, but nothing that you shared is a strong signal of legitimacy.

It would take a perhaps a few hundred dollars a month to maintain a business that looked exactly like this, and maybe a couple thousand to buy one that somebody else had aged ahead of time. You wouldn't have to have any actual operations. Just continuously filed corporate papers, a simple brochure website, and a couple virtual office accounts in places so dense that people don't know the virtual address sites by heart.

Old advice, but be careful believing what you encounter on the internet!
