you will need to burn 217k for lvl 15-99 firemaking, but i would suggest maple logs because you only need to burn 95k of them and they a reasonable cheap, 100k maple logs is around 4mil, which isn't bad for a 99
From level 15 - 30 ( Using oak tree's to get to Willow Tree's ) you will need - 10,952 XP = 293 oak logs. From level 30 - 60 ( Using Willow Tree's to get to Yew Tree's ) you will need - 260,379 XP = 3,858 Willow Logs. best place to cut is around the draynor village jail.
Chop trees. Logs, Oak Logs, Willow, Yew.
Cut oak logs
Maple Trees in terms of exp, willow trees in terms of speed. willows are good for non-members, maples are good for members with like 60+ wc, to make em slightly faster.
you buy 50k worth of oak logs, and bank it. go to the east varrok bank and withdraw 27 oak logs and 7k. run to the sawmill operator and get the logs made into planks. you will end up with 150k
woodcutting-you can sell logs (then oak logs then yews) to make lots of $ by selling them at the grand exchange

Yes, I know for sure Tallahassee, FL has oak trees, lived there for 15 years. And people sell their oak for little or nothing (i.e. 15-20 logs for $15-20), depending on who you're dealing with.
On average, a fresh oak log can weigh between 2,400 to 2,900 pounds per cord (128 cubic feet). The weight can vary depending on the moisture content, type of oak, and size of the log.
In my opinion I think cutting yew and magic logs are great money. yew logs give 600gp-700gp magic logs give 1k -1.2k If you cant cut that you might get some cash you cut oak for some cash.
