Bowcraft

Most Fletchers are also Lumberjacks. Best you gather a few logs before you get started.

Once you have logs, you want to use them, right? Bowcrafting is a useful way to burn up logs and make a tidy profit. Assuming you have 100 str, you should be able to hold 350 boards. Find a fletcher, train up bowcrafting (assuming you have no skill), and buy a fletching tool. Make Bows and sell them to him until 75 skill points or so, then change over to Cross bows until GM. Both weapons sell well and using Razor's sell agent, it's a relatively painless way to GM 2 useful skills and a earn a small house!
