to check audio

I am looking for someone to help me check over some audio I recently recorded. The audio consists of interviews, podcast episodes, and voice-over recordings that are longer than an hour in length. The specific issue I'm having is that some of the speakers and mixer connections are not working properly, and I am experiencing background noise and sometimes distortion in the audio. I need someone with experience who can thoroughly check the recordings and make sure the audio is of a high quality. is a church sound set up
