Exactly. Here's a video I shot that way:
Personally I feel the differences between the DJI and Typhoon for video quality are not going to make or break your business. You need to be able to find good subjects, know how to frame and shoot them, make sure you're there at the right time of day in the right conditions and all the other things filmmakers worry about long before the quality of the camera starts to be important.
The Typhoon has some very useful team modes (make sure you get the Wizard) which opens up your choices when it comes to filming, and you may well benefit from buying some filters, but the tiny improvement you'll get from spending on a different lens won't really mean much to most people.
The bottom line is, if you really want top video quality at any expense, don't buy any machine with a small sensor and fixed lens - that rules out anything under about $3000. But the first thing you need is talent, experience and hard work - look at how many successful photographers and film makers started off with the most basic of kit.
