I'd look at some of the premium monkey making scripts. This honestly depends on how much time you have to run your bot farm. You can either do quick profit on throw away accounts meaning you make the cost of the membership/bond + some profit then get banned. This is risky and requires time as you have to constantly be trading over all profit to a mule acc or something, however some scripts have this built in, or you could work on getting accounts with some levels and running a long term fine i.e doing lava drags or something however the ban rate is still high.
