I work a regular 9-5 job, but I usually get at least two jobs a week. right now its hunting season in my state so Hunters want areal pictures of hunting locations that are up to date, even located a shot buck in a swampy area for a hunter.
I got the $400 package they file for your tax ID and everything it was well worth the price. I think there were lesser and more packages you could get will have to see what fits your needs. the best thing about using them is you get approved fast where as doing it yourself it can take a month to get
that package also included them sending me email when compliance things needed to be done. and your backed by there lawyers for any issues with compliance and paperwork
price varies by distance I travel but average for Hunters mapping I charger $200 for 4 battery flights. Took about a week to get everything back for the LLC and I use the Phantom 3 4K for hi-res pics and video.
