I'm a video producer who's just started multirotor filming. I bought a DJI F550 hexacopter with a Zenmuse H3-2D gimbal. If they'd been available at the time I think I would probably have bought a Phantom 2 with the new H3-3D gimbal. I'd recommend getting something like that to see how you get on. I've done the Resource Group course and, while it was excellent, you have to jump through lots of hoops before you can fly for commercial gain. Worth it if, like me, you want to make a living from it eventually. I'll be taking a flight assessment in the next month but the test is type specific. If you later upgrade to a more sophisticated machine you'll have to have a flight assessment on that too. They have to be renewed every year too. There is no flying training on the Resource Group course. With no previous experience of RC models, I found the flying part relatively easy thanks to the sophisticated multirotor technology but I did get myself an extra day's training on setting up the software and flight controller and how the aircraft works. Hope that helps.
