Fletching. You can do it in like 2 weeks if you no life. Or Cooking. Both are EASY and cheap.
Yeah, I have a life.. School on weekdays. I could only invest about 6 hours during the weekdays per day. And about maybe 9-10 Hours on Weekends (if not doing something)
That's a crapload of time. You could do it in 2 weeks with that amount..
