I edited my post about that but here it is again, all DoW/M classes bring back from the same loot table, so just have them all equipped with the highest ilvl gear possible. For the DoL classes, split them evenly with Botanist and Miner having more and even priority, for example, I have five of mine as DoL classes, so I have two Botanist, two Miners and one Fisher. Just make sure all of your DoL classes also have the latest gear possible with Perception materia melded since Perception does affect the number of things they bring back.
Just in Allagan Gold Pieces, I make nearly 100k daily and then the mats they bring back, that depends on what they are selling for on the MB or use them to craft to sell on the MB. The rare times they bring back stone partitions and neon lights, those can sell for millions each while minions sell for less but many of them in the hundreds of thousands of Gil each.
