To start off here are the MINIMUM requirements
60 Woodcutting
40 fishing
30 coins..
IF you are looking for fast money and you have a fishing level of 55 or above i recomend you fish raw lobsters in karamja and run them to fally (Falador)
Steps
1 get a "lobster pot" and 500 Coins. a lobster pot can be purchased in a fishing store or in the grand exchange..
2 Go to fally bank take off everything on your armer/backback except your coins and your lobsterpot
3 go to port sarim and find the people that say "pay fare" when you right click them..
4 Sail the ship
5 Walk over to the first dock'/ behind bananaah tree lot
6 fish for lobsters
7 when your done head back to fally bank
8 bank and repeat
Once you are happy with what you have go to ge and sell for min price

There are many spots to cut yews.. Its up to you to find the best one for you
Have nothing on except a rune a hatchety (7-9k)
Then go to your Favorite yew spot and cut your yews.. once your inventory is full run to the closest bank and depsit yout logs... the yew longs sell for a lot of money so you shoyuld make pure profit.... sell min price you make about 450gp each it works quite well
I use the yew logs near falador (fally bank is my "station")
i reserved one post below in case i need more room
