part 107 suas is for drones weighing less than 55 lbs but over .55lbs (250 grams) and for flying it commercially (selling the footage) you can fly any of the dji drones with it, and some of djis drones are under the 250 gram weight limit anyway, if you're just flying for fun, you dont have to register any drones under 250 grams or get a license, but if you're planning on selling any of the footage, all drones have to be registered, and you need to have the part 107 license.
To work as a drone pilot in the US, you'll need to get a Remote Pilot Certificate (RPC) from the Federal Aviation Administration (FAA). The process includes passing an aeronautical knowledge test and applying for the certificate. If you don't have a US RPC, you can operate a drone under a certified US remote pilot's direct supervision. You can learn more from the link here: www.faa.gov/uas/resources/foreign_operators
