I craft for free to my Fc people as long as they give me all mats. For random people I charge depending on what they want me to make. Shall we say they want a platinum ring (500k) on market, if you give me the mats I'll charge 50k or 100k. Gotta make some money some how I didn't spend millions overmelding materias and crafting my gear for everyone to have things for free lol
