Money making in Runescape

I have 99 magic, 99 fletching, 91 firemaking and 83 woodcutting, and no money.

How can I make money using the skills I listed above?

Solution 1:

Killing mature grotworms near Port Sarim will harvest about 1.7 Billion gp if you do it for 1 month. You make about 3m an hour! It commonly drops rune items and ores/seeds/armour/potions and the legendary royal dragonhide. It is the absolutly best way to make cash quick.

Solution 2:

This is a high alchemy calculator: http://www.scape-xp.com/runescape-high-alchemy.html You can find the most profitable items to alch on here every day.

Dicing and flowering and such are incredibly unreliable.
