If your computer is good at botting overnight, i suggest something like yews... You will make like 35k/H but if you run that for 10 hours, that's 350k in your pocket that you can use to make even more.
I don't know many ways of FTP money making...
Possibly one of the best ways you can make money is actually become a member .
A week or so ago regular log cutting was around 50k gp/hour. So is mining essence. Just make two mule accounts and bot those, alternating and then sell the accounts once you gain your desired amount of GP.
