Pretty sure you're not going to pay anyone, but here's some food for thought:
1. Skilling Mystery BoxesWhen people train non-combat skills (E.g. Prayer, Woodcutting, Firemaking, etc) they gain 1 point for every second they spend on skilling. When you reach 1,800 points, you get a mystery box. These boxes contain skilling resources, skilling outfits that give bonus xp, coins and junk (bronze-adamant).
2. Charged Skilling ToolsYou can obtain charged skilling tools by paying an NPC gold. These tools gain charges when you use them for skilling. Gathering one resources gives one charge, no matter what tier (Normal/Magic logs give same) When you reach maximum charges, the tool destroys itself but grants you a chunk of experience based on the tool tier. For example bronze hatchet would give you 12,000 experience while a dragon hatchet would give you 188,000 experience. Tools that don't have charges give the same amount of XP. E.g. Harpoon gives 20,000 experience and Small fishing net also gives 20,000 experience.
3. PvP WeaponsPlayers can purchase PvP weapons from an NPC. These weapons cost a lot of money, but are the most powerful weapons when fully charged. They start as level 1 weapons, and can level up all the way to level 95. You level them by killing NPCs/Players in the Wilderness. When you die with the weapons, they destroy themselves and grant the killer the same amount of money it was bought for. They are only powerful in the Wilderness. When used outside of Wildy, they always deal 0 damage.
4. Chicken RunPut player(s) in a big area with a lot of chickens. One chicken is special, and has a 10% chance of dropping a key. Whoever kills that chicken and manages to get the drop wins.
