Looking for Recommendations on Custom Explainer Videos – Who’s the Best?

Hi everyone! I’m in the process of creating a promotional video for my business, and I’m specifically looking into custom explainer videos—not templated ones. I want something that’s tailored to my brand, with a unique script, visuals, and voiceover. There are a lot of providers out there, and it’s hard to tell who delivers high-quality, fully customized work. If you’ve worked with a team or freelancer that creates great custom explainer videos, I’d appreciate your recommendations (and any companies to avoid, too). Thanks!
