some tips to become a good smith: 1. don't limit your repairing arts to low-price arts. the smith point is not based on the number of arts, but on how much gold you spend in smith: 4000 gold = 1 points. So low-price arts cost you the same as high-price arts considering how many smith points you get.
2. get some good customers. You may give some discounts to get more customers. for 20% repairing, I recommend price of 10-20% of repair cost
3. post your offer in your profile, in smith forum, and tell your friends. more ppl know, more customers for you
4. join some clans (big and active is better), give a little bit more discount for clanmates, and become clan smith, you will get some constant customers. (Our clan, #381 Dragon Alliance could be one of your choices, we have about 700 clanmates now and still growing fast.
