A common way for non-members is to kill the cows located in Lumbridge, pick up their hides, and sell them in the grand exchange for about 120-150 gp each.
Mining
Essence - To mine any essence you must complete the 'Rune Mysteries' quest. Non-members have access to rune essence, which can be sold for about 44 gp each. If you are a member and have at least 30 mining, then you can mine pure essence, which are worth 150-160 gp each. The most common essence mine is located in the rune shop in eastern Varrock. Also, if you have are a member and have at least level 66 magic, then it is recommended to use the Magic Guild's essence mine as it's closer to a bank.
Iron Ores - A few iron rocks can be found southeast of Varrock. This isn't the best way to make money, but it is somewhat good for non-members. All you need is level 15 mining, and iron ore can be sold for 90-110 gp each.
Gold Ores - A very good way to make money, especially for members. You must have level 40 mining to mine gold
