Crafting advice

Hey. I need an advice from experienced dwarf. I played all classes back in the days, but dwarves. So when signature was announced it was obvious there will be no better chance, so here i'm newbie dwarf crafter. I did my 1st class transfer and begin to prepare my first shipment of SSD's, first on paper of course. So as i have low budget for now my plan was to buy lowest price D-grade boots from Giran shop (22990) to crystallize them for 38 crystals and buy ore 275*38*3. This will cost me 54340a. Regular price of SSD's are 10a atm. So 156*38 = 5928*10a = 59280 - 54340 = 4940a profit.

My questions are:

  1. Did i calculate everything correctly / not miss anything?

  2. Is it normal to have such profit on SS (I thought the income would be higher)

  3. How can i maximize income beside crafting items by myself?

Any advices are welcome.
