Quick question

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,

These accounts have little demand. Why the firemaking? It's not useful. I'd say OSRS, though. You could probably get best profit selling accounts @ 61 woodcutting.

 

I already made one on RS3. How much could I expect with 99 wc and fm?

 

Little to none. Both of these are very easily gotten to 99, without any effort and money.
