try questing thats pretty good money
You could buy and resell upgrades. E.g; Buy for 8m sell for 10-12m
do fight kilns for people, if you can get customers it's like 30m a pop
Any mind numbing skill you hate to be honest, people will pay a fair bit for agility as its a bitch and you don't need bank access.
Most skilling is great for money-making, especially if you're hand training which I'd pay extra for since there's extra safety for the account.
There are not many actually vouched skillers. You will get customers.
Skilling is great! I just did 85 - 96 herblore for a rich staker for 75m. That took like 12 hours and I did it by hand tho.
