You need to complete the Earning a Living quest first which can be found here: http://www.sao-rpg.com/topic/6380-%C2%ABearning-a-living%C2%BB/

I'd also advise reading up on the enhancement guide and profession guide found in the tutorial section here:http://www.sao-rpg.com/topic/6372-complete-profession-guide/
http://www.sao-rpg.com/topic/6691-enhancement-guide/

to give you an idea of what you'd like to be :)

I have completed the quest and am currently a beginner blacksmith. Thats why I am asking lol

Ah if you've done the quest, then yeah you go right ahead and just open up shop.

You need to do your first post as the shop thread detailing your shop, prices and stock and all the crafts and people buying stuff go on underneath that :)

If you want take a look at the Amethyst Boutique which is my shop for an idea of what I've done, b
