Quick question

[Mythvs]

I've recently become interested in rs3 again, and have two simple questions. If I level firemaking and woodcutting to 99, and want to sell it, how much would someone realistically buy it for? Lastly, would it be more profitable to sell an rs3 or OSRS with 99 fm and wc?

Thanks,
Mythvs

osrs would likely be more profitable but you probably wouldn't get very much
