Once you have your Part 107 cert, you could sign on with Zeitview. Clients hire them for various types of drone jobs all over the country and they pass those mission offers on to pilots who are signed up with them in the area the job is in. You can set a radius of how far you are willing to travel. You can pick and choose which jobs you want.
Zeitview offers free online training courses to build you skillset and make you eligible for more types of missions. They offer missions for various types of drones, too. You register which drone(s) you have with them and they offer missions accordingly. They won't offer you a thermal imaging mission if you don't have a thermal capable drone. Many of the jobs involve using an automated flight app (I use DroneLink, which I paid for) to capture a series of photos they can use to create a 3-D model for their clients.
There are other types of jobs, too. I have driven to locations just to snap one "birdseye" photo of a building's roof on multiple occasions. These Zeitview jobs don't pay much, but it's a great way to get some experience and learn how to deal with different types of missions and issues that can arise. Sometimes the job offers just aren't worth it for the pay offered, due to the travel distance. Sometimes in this instance, I've been able to take multiple missions in the same area to make it more worth the travel time and gas.
Many times you will need to use LAANC to get airspace authorization to fly in certain areas. On a few occasions, I have needed to request a waiver from the FAA. This is good experience for you as well, so that when you start your own business, you can take on jobs that others might shy away from due to the added complexity.
Zeitview doesn't have a great reputation due to their low pay, but as I mentioned, it's a way to get some experience and training and make a couple bucks in the process. Look at it as a paid internship. Despite comments I've read about them, I've found their pilot support to be very good. If you have a problem or question, you can email them and they will get right back to you.
For the record, I'm not a Zeitview employee trying to promote their program or anything like that. I'm just sharing what has worked for me as a way to get some experience, training and confidence. I still use Zeitview but also do jobs for FlyGuys, Dronegenuity and some direct clients, all of which pay better than Zeitview.
Come back and give us some updates on how your journey into the commercial drone industry is going. Good luck!
