Can the community recommend a blockchain analysis firm?

Hello, we are in Arizona, if it matters. My girlfriend wants to pursue a cryptocurrency investment that she recently lost to a scam. She is aware that the chance of recovering her money is slim to none, but she is thinking to hire a blockchain analysis firm. At this point, everything looks like a potential scam, and we need some help determining a reputable firm. Thank you in advance! [Edit] Well, my post was auto-moderated for not being long enough. I’ll add that she had between $350,000 and $400,000 in cryptocurrency on a TradeStation account. TradeStation emailed her that it was shuttering its cryptocurrency service and recommended she move her money to Robinhood. Long story short, she started talking to hackers somewhere along the way, and the money disappeared. We went to the FBI, which had us fill out an online form.
