Efficiency is the name of the game. The markets are there, but they are competitive and price is a big selling point, if you aren't efficient you will find yourself working for minimum wage really really quickly. Automate as much of your workflow as you can, learn to shoot quickly and efficiently, stack shoots one after another, and you can make it pay ok.
Only way to make it pay what I would want to make a real living out of it without running yourself in the ground would be to employ others IMO.
