rather than doing it yourself if you dont have the other crafting classes leveled you would be better served by locating a 2 star HQ crafter on your server, since at this point any high end crafter worth the time can easily HQ it from NQ mats. I dont know about your server, but on Famfrit you can either go to Rev Toll or Limsa and shout and most anytime of day you can find someone who has mastered all the crafts. If your providing all the Mats they have no real excuse to charge you more than a few thousand gil for a Tip unless they need to use food or are just greedy

The most I've ever asked for for a tip was 5k to cover Food / Time myself, tho I've had people give me 20-25k of their own choice occasionally.
