Yes, I have my 107 license. I see I will need FAA approval. The 107 regs mislead me. If I was a hobbyist, then this applies: "Provide prior notification to the airport and air traffic control tower, if one is present, when flying within 5 miles of an airport." But since I am flying commercial, I have to get an FAA waiver because its Class D to the surface. So, if they ask me to fly, I have to say wait a couple of months so I can get permission, and by then the car show season is over. I just need to proactively file for waivers in all these small towns around me (with airports) so I don't have to turn down opportunities.
However, a hobbyist can just ask for permission from the local airport. <sigh>
