It is possible to have the crafting steps commissioned, provided the crafter has the recipe for that given step.

You may wish to consider doing the other Kingdom of Sky Heritage Quests and Signature Quests (Blood of the Brood, Draco Mortuus vos Liberatio and A Mark of Awakening) concurrently with this quest. Many of the steps take you to the same instances.
Steps
The first task he sets out for you is to help him (in other words, do all the work) get trophies from three "dragons."
Azdalin in Tenebrous Tangle ( 646, -163, 556 ) Copy/waypoint 646, -163, 556 (61 Heroic ^^^): big lizard that wanders the path Breeding Grounds . He spawns when someone on this step of the quest gets to the island.
Gylton in Sanctum of the Scaleborn ( 27, 85, 382 ) Copy/waypoint 27, 85, 382 (67 Heroic ^^^): drake that wanders around the hoards of droags and drakes in The Audience Chamber above The Gorgs' Pit. He has a lot of hit points and respawns almost immediately after being killed.
spawns as a NPC and is not directly attackable. Right click him to pluck a scale from his NPC form then leave quickly as once he realizes what has happened he will begin attacking. (You may have to kill him, I did.)
Be very friendly and cooperative in your conversation. If you say the wrong thing the old man will grow tired of the conversation and you will have to start over.
Retriever the oak shaft from a chest in the Sanctum of the Scaleborn ( 23, 121, 307 ) Copy/waypoint 23, 121, 307 or ( -3, 122, 334 ) Copy/waypoint -3, 122, 334, above The Audience Chamber at The Lair of Scale
Go to the forge ( -116, 65, -34 ) Copy/waypoint -116, 65, -34 in Sanctum of the Scaleborn and craft the Re-shafted Wurmslayer
While you must be a level 50 artisan to scribe the recipe, it is a level 60 Geocraft combine. If you are lucky or skilled at crafting you can do this with lower than 300 Geocraft.
You must create a "pristine" item or you will fail and your resources will be lost.
Return to the old man. He will give you a level 55 artisan recipe for a Sharp-bladed Wurmslayer.
