It's so much harder to do than you would imagine. First of all, the two biggest hurdles are being able to hear what's being said and being able to see what's going on. That sounds pretty simple but it's really not. Most pool rooms are pretty dark with very bright lights over each table. Our eyes adjust very quickly and easily but not so easy for a camera. On top of that, hearing what's going on would require wireless lav mics for everyone and someone monitoring those. All and all, a bare bones crew would require 3 camera guys and a sound guy at the very least and one of them would have to be directing the crew as well. Each of them making between 500-1000/day. Then, you'll need an editor and story producer to piece together the hours of footage and create a story worth watching. Each of them will make about the same rate. Add in meals and lodging for the crew on the road… would be a good idea to get production insurance. Also, assuming you had all the equipment needed... So give or take $100,000 for a month of work for a decent product. Could be done for less, but I wouldn't recommend it.
