II- "Step two"

Ok now you should be at level 20 fishing, after fishing for hours on end. Now you use the lumbridge teleport and get your fly-rod, go to the river with the fishing spots in the center of lumbridge and fish there, untill you can get pike, and then keep fishing.
But remember all this time you have to cook your fish!
Now at level 30 fishing, its all about the hard work, you should be able to acess the Chefs' Guild
Go in there and cook pie like there is no tomorrow. And after you have 20 pies, sell them and get like 3000 GP and then head off to lumbridge to fish, again.
