What is an easy way to get rupees in Zelda Twilight Princess??? Any cheats?

Im trying to get the magic armor. Need donate money first and wondered whether if there was any faster.

* Collect the gold bugs and drive them to Agitha in the castle of the city, she gives him 50 rupees for Error 100 for a pair. * Kill the flocks of birds flying in some parts of Hyrule field. The Gale Boomerang and Z-Targeting lets you drag them close of being killed by a sword. * Take your flashlight and head on over to Kakariko Graveyard. There you will see two unlit torches. Get that flashlight (you need to have some oil left in it) and the light of torches. A chest will appear with 50 rupees. Still not enough? Then push both of the tombstones pushable. One will have a piece yellow rupee, which is 10 rupees. * In Kakariko, there's a cache 200 rupees at the top of the Sanctuary (the bell). Take a Cucco (chicken) and head up the ramp of land at the southern end of town. Glide and climb your side of town to the hot springs. Glide across the street to the roof of the bomb shop and climb the ramps to the base of the watchtower (a Goron the clock at the bottom, the kid from upstairs). In the area of observer Goron's, glide to the scaffolding embedded on the cliff near the Sanctuary. Glide to the wrecked roof of the Sanctuary and the use of a pump down arrow brightness inside the church bell.
