How do you make gold?

I made a 600,000 just from selling spots in my Normal raid. I send out a message in trade that I’m selling full Normal clears. People whisper you and ask how much, so I tell them 100k each. I explain to be online at 9 p.m. Central and I’ll send an invite if interested. Had 7 people interested, but one no show. So I just formed a raid in the premade group finder and sent invites to the 6 that still wanted to come. Then I filled in the other spots with people that had decent raider IO’s and gear levels. It actually went pretty smoothly until Fryakk. Then I had to kick 2 low dps, but not my paying clients, lol. I brought in 2 other dps and we mopped it up. Wasn’t pretty, but I got 600k for just putting a group together. Worst case scenario, group falls apart and I had to refund money, but went so good, I’ll do it on some more alts and milk it for more.
