Note as I post this, this method worked perfectly well and I've decided to share it as I'm now F2P and don't plan to play runescape again. This guide involves the Tai Bwo Wannai Clean Up minigame so its a P2P guide.

Requirements:

Jungle potion: http://www.tip.it/runescape/?rs2quest_id=38
Enough for 10k Trading Sticks (60k).

Recommended:

A House in Karamja, Beast of Burden.

Preparing:

Head to the GE and buy 10k trading sticks for the price of 60k (the lower you pay the more profit you will make), Once you recieve your trading sticks buy 10 House teletabs (if your using the house method). Take all equipment off but equip a ring of dueling. Put the trading sticks in your invent and the house tabs, if you have a beast of burden summon it and teleport via the teletab to your house (which should be in Karamja) then exit you house so your on the island.

Arriving at the Minigame:

f you took the sensible method of teleporting to your house in Karamja you should run south then a little east until you see "Gabooty." If you don't own a house in karamja, you will either have to teleport via a glory amulet, take the boat from Ardy or teleport to Shilo Village, However I don't suggest doing any of these as it will take to long.




The red line shows the suggested route you take, and its about a 30 second run from the house portal, the yellow lines are alternative routes but will take longer.

Once you arrive talk to "Gabooty," and click trade and he will show you what he has for sale.



As you can see he has many items for sale, but he only accepts trading sticks for the items (hence why you bought 10k+ tradings with you).

Prices for each item in trading sticks:

Tribal top - 360
Villager robe - 300
Villager hat - 240
Sandals - 120
Armband - 180

Buy as many as possible of the product you plan to sell, then bank by teleporting to castle wars (using the ring of dueling you should have equiped).

How do I make money with this useless junk?

Here are the current prices of some of the items on the 07/09/2008




As you can see, The ones I highlighted in red are good profit maker's, heres the math for just the villager hats - were take the highest priced one for example.

A villager hat costs 240 trading sticks, a trading stick costs 6gp so 260 X 6 = 1560.
A villager hat sells for 2,524 on the Ge minus 1560 = 964 profit, using a terror bird you can bank 38 items a trip. 38 X 964 = 36632 minus a tele tab + a ring of dueling use = around 35k a trip. A trip using a terrorbird + house method can be completed in under 3 minutes, Creating a huge profit if you do this regularly.

The items I highlight'd in blue are items that I havent yet tested, and the one I highlighted in yellow seems like a good money maker but once again I havent had time to test it. All villager hats sell, I bought 400 hats and it took 24 hours for all of them to sell and the GE price.
