There are many hobbiest that, like myself, see the benefit of drones in business. I instantly recognized it when seeing my first drone review a little more than 1/2 a decade ago.
If you are one of these individuals and are looking to getting your Part 107, I thought I’d list a few things here that can aid in being able to do so.
I would suggest purchasing a Part 107 course, from a reputable source. I went with Greg R. who co-founded and runs Pilot Institute. I actually used his Udemy course prior to it blooming into Pilot Institute. It is a GREAT course. Tons and Tons of videos, quizzes, and explanations from an actual commercial pilot.
Some might say that they just watched an hour-long video on Youtube and passed. That might work for some, however, for me personally, I wanted to dig DEEP into every aspect of being a 107 cert holder - weather theory, airport operations, pilot attitudes, load and balance, maps, NOTAMs, etc., etc. These are all things that PI goes into, in great detail.
If you are serious about getting a business going in this industry, I say why not treat your 107 like a college course and study study study until it is second nature.
In addition to getting a 107 class, I also purchased an iOS app called Remote Pilot Test Prep. It has all types of quizzes, some of them the same length as the ones you’d get at a testing facility. This coupled with the Pilots Institute class helped me pass with flying colors.
As a side note, as of right now, when your 2-year re-cert is due, you no longer have to go retest at a center, it is all done online and free. Best thing ever 
If anyone has any PArt 107-related questions, feel free to ask away. There are other 107s here that can answer as well.
