A Few Ways to Make Money on RuneScape

First, if you're not a member, you could start by cutting down trees and selling the logs at the grand exchange in Varrock and sell it for either the fixed price or set your price higher or slower. It is recommended that you first have some decent experience in woodcutting because normal logs won't sell for much money.

If you do have some decent experience in woodcutting, you can cut down oaks or other trees that require higher levels and they would sell for more. If you don't have that much time to be leveling up your tree cutting to sell good logs then I would recommend doing the "rune mysteries" quest and then, after you complete it, you should mine a lot of the rune essence and then when or if your inventory is full, you can then sell your entire inventory of the rune essence for about 28 gold pieces each or you can sell it for a higher price.

Another good way is to go to Al Kharid and bring your best armors and weapons and start kill the guards non-stop and get the herbs and earth talismans they drop and then deposit them in your bank account and then when you think you've had enough, withdraw them as notes and then go to the Grand Exchange in Varrock again and sell them there. Herbs are about 1k each and the earth talismans about 512 gold pieces. To do this though, it is highly recommended that your at least level 40 or higher in your combat level. Another, but very dull way of making money is by selling bones, although you do get about 100 gold pieces for them. I hope that I helped you on making money on RuneScape.
