How Do I Choose the Right Editor on a Budget?

I’m finishing up my manuscript and trying to decide on editing options without overspending. I’ve been reading about affordable book editors and wonder if they can really provide quality work. Can a budget-friendly editor still improve clarity, flow, and reader experience, or is it too risky? For authors who’ve hired them before, did the results meet your expectations, or did you notice compromises? I’d love tips on finding reliable editors who won’t break the bank.
