Ping is on Coalition of Tradefolk Underground.
So doing any of the quests for C of T Underground will raise faction with him.
The links below are the two that I did.

Being a Druid made this fairly easy since both start in the same area.
I bound myself at Rebby and Janum's location and gated to them once I rec'd the messages required to give to them.
When I rec'd the secondary items from Rebby and Janum, I just had a short run back to the quest givers. (Nestral T'Gaza & Harkin Duskfoot) Both are Rogue GM's
I was able to raise the faction with Ping fairly quickly since you can do both quests at the same time.
