Electrical panel inspection needed in Portland - want to confirm two businesses are on separate meters

My business shares a building with another business, and I’d like to have an electrician come inspect the electrical panel to confirm that the two systems are actually separated.

We do have two meters, but my power bills have been looking suspiciously high for the amount of usage I have. I’d like someone to verify that I’m not somehow paying for part of the other business’s electricity.

If anyone has recommendations for a reliable local electrician or small company in Portland, I’d really appreciate it. Thanks!
