Looking for goldfarming methods

I'm currently looking for decent goldfarming methods to make a bot, and eventually a small farm. I'm willing to share the bot via TRiBot if the method is actually viable. I'm looking for a method that requires minimal reqs, and requires nothing to purchase, purely to sell and is unsaturated.

Let me know via PM, thanks

 

Can there be skill requirements? I have some methods in mind, but I'm not sure if they are botable or even scriptable. Are you writing the complete script yourself?
