There are a number of money making methods in the game.
The most obvious example with the information given is woodcutting.
Given these stats, I'm going to assume that you have reasonable stats in everything else, for the sake of simplicity.
If you have completed Throne of Miscelania (and, optionally, but desirably, Royal Trouble), then you can use Kingdom Managing to make money.
The profits on each thing vary depending on current market prices, so check this calculator can be helpful to optimize profits.

There are several ways to earn money in Rune Scape which everyone knows, like cutting yews or killing Green (Wildy), Blue (East Falador) or Black (Same dungeon than blue) Dragons.
But these methods will make you play and click for ever and you will only get a decent amount of money with it.
If you want to know some money making methods that will make you really rich, and with rich I mean earn over 100M per month, I will sum them for you.
I haven't played for over a year now but
last time I played I earned over 150M the last month.
I got a bank of Green h'ween, Santa DClaws and 45M cash.
My three methods: Dual arena Scamming (look on youtube for useful and powerful dual arena scams) Merching (also decent you should do this smart and with some friends, create a clan and make other people suffer from your profits) Dicing!!
With his method I earned most of my money.
I never really liked the game itself
but I did like making money.
I created my own clan with website .
The whole dicing process is explained at the clan website which is still online.
Ít is important not to scam people because even if they win they will always come back to dice again and eventually they will lose because you got 55% chance to win
and they got 45% chance.
I started with 30M which I made with merching (there are plenty of merch guides on the Internet) and with that 30M
I did 500k bets max
, that means a 1M pot because you put 500k in the pot from yourelf.

What you can do still is to buy seeds (cabbage at 3gp, hammerstone at 5gp, Jute at 5gp, and asgarnian at 4gp)
then sell them to Olivia in Draynor Village for more cash (Cabbage 7gp, Hammerstone 18gp, Jute 25gp, asgarnian at 16gp)!

the math - 3.000.000 gp (3m) / hour, playing for an average of 4 hours a day results in 12.000.000 gp (12m) per day, if you do this for one month it'll result in 360.000.000 gp (360m) / month
