In order for you to earn that much money, you must offer something to the marketplace. People around here do signature designs, logos, specific services, mixing, mining, etc. and you must be able to meet that standard for competition. Asking for ideas without simply stating what skills you posses means that you vaguely know about the background of this forum.
Most services being offered revolve around making codes and signature campaigns. Try your luck with those and just freely wander in the forum to learn more about it.
