Okay, I'm looking for opinions here, and I have a story behind this.

So, I was helping out a fresh 50 FC member get some starting gear, to help him with getting into the endgame. Now, I'm a 3 star omnicrafter, with 4 stars spattered here and there, as most of us are. However, I really didnt want to go through the time of crafting it, as it was late for me, and I had to get to bed. So, I contacted my local crafting linkshell, looking for a 3 star goldsmith. I got one, and asked for a 5 piece set of BLM i90 accessories (the Diamond set). Now, I looked up the material cost of these items, and the base cost to produce the items would have been around 600k total, and the market board cost of the items was 300k apiece. I originally offered a mil for them, but we haggled, and I agreed on the price, being 1.3 mil.
Now, I wake up, and find that what was delivered was 3 HQ items, and 1 NQ ring, and the price asked for was now 1.6 mil. Needless to say, I did not even pay close to that price.
now, and TL;DR: if another crafter is outsourcing a crafting job to you, do you over inflate the prices for them? or do you give yourself a small margin, and hope that it drives more business in the long run?
