Few ways to make some cash!

[Dark Chevard]

Woodcutting and Fletching:
You only need level one fletching and level one woodcutting, first of all if you cut 520 normal logs this will take you about an hour if your 50+ w/c and then you fletch them into arrow shafts that makes 8200 arrow shafts, which can be sold for around 130k.

Fletching and Alching:
If you have high enough fletching you can make yew longbows which are alched for 720gp ea and this makes easy money and many members do it.

F2P Woodcutting:
Firstly add a person called "Wood Co Ltd" who will buy normal logs for you at 50gp ea this can make you a nice little bit of pocket to start you off.

High Mininers and Smithers:
Get 4000 coal pieces and 1000 mithril (this will take a little time but some people can buy it for cheaper prices etc.) Smelt the ores into bars and then smith them into mith plates and then alch them which will give you 622K, You can try this with steel some say it works bette as less ores are used, so you'd have 2000 iron ore and 1000 coal.

Buying, Making, Selling
A good way to make money is to buy an amount of steel bars or even make them yourself which you can buy for about 400-500gp ea and make 1 bar into 4 cannon balls and cannon balls usually sell for 200gp ea and you have 4 per 1 bar which means you have 300gp profit if you do it in big bulks it can equal big profits.

50+ Rangers:
If you have 50 plus range then this is quite good way to make money is to go down to the watch tower enclave at Ogre city where blue dragons spawn there is plenty of rocks to hide behind so all you have to do is range you can make 4k per dragon because of the hide (2K) and the bones (2K) plus the loot some will say why not goto heroes guilded where one blue dragon is jailed but it is too populated.

Quick Nature Essences:

Put all of your Rune Essence into bank notes. Take 4 times the amount of gp as you have Essence.
Run to the Shop near the village.
Sell your notes to the shop and buy them back so that they're in real form.
Craft Nature Runes at the alter.
Run back to the shop and repeat this is the processes

There are loads of boring methods that I have left out hope these few help you.
