Need help syncing audio

I have a podcast and need help syncing the audio. It’s not as simple as using a software I know how to do that. So I recorded video and audio on one camera and the audio of the second person on my phone using a wireless mic. The first 30 mins of the video the audio is synced up but after that the audio of the independent mic is ever so slightly lagging. I would love to have it synced up properly and looking for someone with experience in this field to make it happen. Should be a quick fix for someone who knows what to do. I will give you access to google drive to complete the task.
