Woodcutting/Fletching:
Ok, go to ::wc or ::draynor and start chopping tree's. Get your WC to about 110, or enough to chop Magic's. (*NOTE*) - Make sure that you have about 105-110 fletching, or you can't do this. Fletch all of your Magic logs, and then sell them at a store for about $120,000 or 120k a piece.
Farming:
Ok, go to ::wc again, and take about $900,000 or 900k with you. Just enough to buy 30 Seeds. Plant them and sell each Herb for $152,000 or 152k a piece. Easy peasy, lemon squeasy...
Crafting:
Ok, go to ::skills, and buy some 'Uncut' Sapphire's. Chisel them until you can do another stone. Keep doing that till 'Uncut' Dragonstone. Cut them and sell them for alot. (Unknown Price ATM)
