Enchanting Services (Barter)

I've had 3 different people ask me to do a Lifetransfer cast on their weapon just in the last two days. I'm happy to do casts for people, however, I have no need for money so I would prefer to barter for my services. 

Here's what I am currently looking for, basically any of the rift materials found in treasure chests, namely:

* Seryll lumps (highest priority)
* Adamantime lumps / ore
* Rift crystals
* Rift wood
* Rift stone shards

My current casts are falling in the following ranges most of the time:

Lifetransfer: Normal (45-55), Lucky (70-80), Highest (99!!)
CoC / WoA: Normal (60-69), Lucky (75-85), Highest (93)
