NFT advice before I get eaten alive by the sharks

I am in need of a link to a list of art agencies that work with NFT. I put one toe in the market yesterday and the response I got today was both exhilarating and terrifying. But the sharks are already circling so to speak, I've been contacted by multiple people, a few I'm fairly sure aren't people at all, but actually bots and it's clear I need representation I can trust asap.

Any singular suggestions of agencies would be helpful as well, as well as any advice for the immediate future. If it helps I am very familiar with crypto and how it works, however this is my first foray into NFTs so I may need some clarification on some of the jargon, just FYI.

My first instinct is to unlist everything I've listed NOW so it can be managed correctly. Would that be a bad idea or no?

Thanks so much for any advice.
