What about mining iron ore and smelting it into bars, and eventually smithing those into iron platebodies? You can use Tip.It's smithing planner (here: http://www.tip.it/runescape/?smithing_planner) to help you out a bunch, I know I used it in F2P (back in the day...) to make a mil off of steel bars. And if you used the Stealing Creation hammer, you could score double experience in the same amount of time (Stealing Creation guide here: http://www.tip.it/runescape/?page=stealing_creation.htm). As for basic ideas, gathering and selling secondary ingredients for Herblore is always good money. None of those are gonna get you 4+mil any time soon though, that's important to realize right now. Just play the game, level your skills, and have fun! That's how I made a couple mil,with friends and good times skilling/training combat. I hope that helps! That's just one idea though, you could woodcut, fish, hunt green salamanders, kill green dragons... the list is pretty long. Make sure you check the Archive of Wisdom (AoW link here: http://forum.tip.it/viewforum.php?f=103) Toooooooo long of a post. Sorry bro.
