How can I have my GPG public key signed by a CA?

Hello friends,

I have been using GPG encryption with work for exchanging attachments via
email with our partners. While I am trusting that he is sending me the
correct GPG key and it's signed, I can't really validate this signature as
it's self-signed. Is there any sort of the third party GPG certificate
authority that would sign these, or provide another level of verification?

Wonder how others share their public keys as well, or work with these types
of encryption details while sharing files and attachments.

Thanks,
Robert
