Starting off a league you can do several early things for profit: uber labfarm (juggernaut something), delve fossil farm (pathfinder bv, more imoortant to know delve itself), generic low-mid tier map mf on maps with decent divcards (anything that goes fast with some iiq gear, probably something bow related) or you can bossfarm starting with norm atziri and move up to more end game ones as you have more currency to invest (arc/gc mine is probably the best budget there)
If you google build for any of these you’ll find plenty of guides
