Honestly, the easiest way to make currency in standard is just geared up with ~60%MF and run a high-density map with just alc since you don't have enough currency for flipping. If you are starting out with low currency, do not add any investments to your map because you can't afford the loss of profits due to RNG. Just alc and go nets you the best currency in return given that you don't have enough resources to fully chisel, sextant, fragments, and Vaal 100 maps. I farmed up a headhunter within a week with just 3-4 hours per day doing it this way in Incursion.

More details on my method: -Have a dump tab to deposit my loots -Pick up all the uniques (These uniques will help you sustain ALCS if you vendor them) -Look for uniques that sell for a decent amount with high rolls and sell them. -Alc maps in sets of 50-100 and rerolls maps with mods you don't like. -Do lower tier maps to infinitely sustaining them (look up a video on how to do that)

Hopefully, within a set of 50-100 maps, you should be able to find 1 exalted orb or 1 divine depending on your RNG. I would suggest sticking to one map so that you'll learn all of its layouts and are able to complete it more efficiently.
