You can always spend some time to farm materials to sell to players in East Commonland Tunnel for now. Once you have some savings you can start levelling and make money at the same time.
Unfortunately this means you need to leave the Qeynos area. If you want to stay near the Qeynos area, do the
Bandit Sashes quest.
Otherwise, here are my suggestions:
To save up plat (can do as long as you are not level 1)
A stack of bone chips - 10pp
A stack of spider silk - 10pp
A stack of spiderling silk - 10 to 20pp
Low and medium quality Wolf/Cat/Bear skins - 2-5pp each (these kind of suck as they are heavy and doesnt stack)
High quality bear skins - 30pp each
The better idea is to buy a sewing kit and make
leather paddings to sell to players. One stack now is 100-200p.
When you are around level 12:
Greater light stones from wisps can sell to players for 10pp
Another alternative (which really needs some luck as the camp is VERY popular);
The nybright sisters camp in
Lesser Faydark (#14 on the map).
There are basically 4 mobs here that drop bronze weapons. They sell very well to npc vendors. If you are not killed on sight to the woodelfs there is an npc hut (#10 on map) that you can sell at. If not you can run to the druid rings (#6 on map) in
Steamfont Mountains to sell.
When you are 16 or higher, i suggest you make a trip to
Najena in
Lavastorm.
Kill the elementals in there and look for the following drops which sells well to players (and you can get exp as well):
Earth Elemental - Drop of mercury (~30p)
Fire Elemental - Lava Rock (30 - 50p)
Mist Elemental - Swirling Mist (30-50p)
If you kill the magicians, they have a chance to drop the
mage focus items which you can sell or 100-200p each
You can stay in Najena till the mid 20s if you like. If you are bored or when you think the exp is getting slow, head to
Mistmoore Castle.
Just look for groups and join them. When you first start, the best money comes from the Gargoyles which drop Gargoyle eyes that stack and sell very well to npcs.
As you start moving up into the deeper part of the zone (namely the castle area), mobs starts to drop
Essence of Moonlight.
There are smiths out there who pay 50-80pp for each essence.
By this time you should be all set.
The above is my suggestion for anyone who don't mind sticking to just a few zones to level while they make money. And since the items drops off common mobs, you dont have to worry about people camping them all the time.
