I personally find Avantoe to be wonderful, safe farming profit, but considering that's at level 50 it's out of the question. If you're looking for some spare woodcutting xp you can chop Mahogany trees and make planks out of the special logs. I don't have any exact figures, but it's pretty much afkable and the mahogany planks sell for around 2k a piece. The logs themselves chop fairly quickly and go for 300 gp. I also find them to be the best woodcutting xp outside of ivy. If you despise woodcutting, then collecting big bones from the Hill Giants Resource dungeon is decent melee xp as well as good money (500 gp a pop and a chance of level 1 clues as well as a high chance of limpwurts, which are around 1.5k). The resource dungeon tends to be less crowded. If you feel like Hillies are too nooby for you, Moss Giants work too.
