Where Can I Find the Best Proofreading Services?

[LuciaBrain]

I'm about to finish my book, and now I need to find the best proofreading services to make sure everything is polished before publishing. I know editing and proofreading are different, but I specifically want a proofreader who can catch grammar mistakes, typos, and inconsistencies.

Does anyone have recommendations for reliable proofreading services? Should I go with a freelancer or a professional company? I don't want to risk putting my book out with errors that could hurt my credibility.
