This is something you'd have to really experiment with yourself, trust me, I asked for advice on my old TW character and every time it turned out horribly, I spent about 25 bucks on Character Cards, just experimenting, and it didn't turn out well for each one, and when I made one on my own personality and interests, it turned out REALLY well, and I still play it and have fun with it till this day.
All I have to say is if you want to make some real cash at higher levels, go with tailoring shirts and stuff like that, you can charge whatever the **** you want and get away with it because people are desperate for armor. It can be a gamble though because of materials you need to buy.
