Hire on three things: who does the work, whether they own your file end to end, and whether they can show you what they changed rather than just claim it. Title, location, and marketing polish don't tell you any of that — the method does.
Ask the specialist directly: will the person who reviews my file be the one who works it, or will it be handed off? Do you keep access minimal — view-only for the free review, QuickBooks' accountant access for the work — and leave my bank logins alone? Do I get a written scope and fee before work starts, and a change log I can hand to my accountant afterward? A specialist worth hiring answers those plainly and welcomes the scrutiny — the work should be verifiable, not taken on faith. The clearest way to test all of it is the free review itself: you see how someone reads your file, and how they explain what they'd do, before you owe anything.
